The greatest discovery you never heard of | Rebecca Costa | TEDxSantaCruz


Translator: Theresa Ranft
Reviewer: Peter van de Ven Hello, Tedsters. OK, this is going to start out
on a negative note, but it’s going to get better. And what a hard act to follow, right? It’s not easy to be me
on this stage right now. So be kind. Let me be the first to tell you
things have gotten too complicated. The other day, I had somebody
try to explain to me the economics behind
a national healthcare program. And I thought my head
was going to explode. I should understand
how we’re going to pay for it. So I went to Alan Dershowitz,
Bill Richardson, and some smart people
that should know this stuff. And they said,
“We don’t understand it either.” Yikes! But it’s not just that. You know, I’m driving here in my car
and I’m trying to load my CD player, and I’m trying to put the address in,
the nav system and all that. And I realize, “Yeah, that’s why
they made a log and it’s texting” because I can’t figure out,
like there’s a limit to what I can do. I’m too stupid, so they got to say,
“You can’t drive and put your CD in and fiddle with your nav system, and text. What are you thinking?” So, I got to thinking, “What’s going on? Why can’t we solve our problems?” Maybe there’s a connection between
why we can’t solve our problems anymore and the complexity of the issues we face, whether it’s climate change – we still have 65% of the people
in the United States that don’t believe
that global warming is happening. Now, can I balance that against
the 1.5 billion with a “b” measurements of the Earth’s surface temperature
that we’ve taken since 1880. Now, if that isn’t enough data, I don’t know what it’s going to take. OK, 1.5 billion measurements
since 1880 – it’s not theoretical anymore, OK. It’s gotten really complicated. So, what I’m going to do here
in the next ten minutes is I’m going to try to show you why our problems
are not political anymore, they’re biological. We’re up against an evolutionary limit. Now, one way to think
about this is two clocks. One clock is the clock of evolution, discovered by Charles Darwin
152 years ago. And every time the hand moves,
it’s a million years. I need a new appendage
to do all the stuff in my car, I’m not getting one. Neither are you. Can’t drink my coffee,
drive, and work my nav system. We’re not getting one
for many millions of years. It doesn’t matter what you need,
you’re not getting it, because we’re all
in the same biological spacesuit, and this spacesuit can only adapt
in million-year increments, it’s very, very slow. Now, with the second clock
is human progress. And every time that hand moves,
it’s a picosecond, right? Apple’s already come out
with a new version of the gadget
you’ve just bought last week. (Laughter) Guess what? While we’re sitting here,
there’s ten more free apps you can get. I don’t want any more free apps! Let me be the first one to say,
“I don’t want any more gadgets, I don’t want all the free stuff
that came on my PC and I’m scared to take off
because it might ruin my work. I don’t want any of that.” What happens when complexity races ahead of the brain’s ability to understand it? Well, we know by looking
over ancient civilizations, we become gridlocked. We can’t solve our problems. One of the earliest signs
is we begin passing them off from one generation to another, and we know they’re getting worse. The world I am passing off to my children is significantly worse than the one
I inherited from my parents. An uneven rate of change
between biology and human progress causes a lag, causes a gap to occur. All of humankind,
every government, Mr. Obama, you and I have hit a limit. When we’ve broken down the human genome
between our nearest ancestor, the bonobo monkey, in ourselves. I don’t know if you know this, there is only a 1.7% genetic difference
between the bonobos. I think we’re leveraged
the hell out of that! (Laughter) While I’m talking to you, the men are not trying
to have sex with their chairs. You’re not throwing food at each other. If you’ve ever studied bonobos,
that 2% difference is massive! (Laughter) We stay in our lane, we … my God! So, I’m really impressed. But folks, there’s a limit to this. If you took a Neanderthal,
you dropped him into Times Square today, he wouldn’t function very well. And if you put us in a time machine
and jet us into some million years ahead, we’d look like a Neanderthal. We are a work in progress,
and there is a limit to it. And we can argue whether we hit
that cognitive threshold today, or 50 years from now, 100 years from now. But eventually, if you’re logical, if you’ve got
one logical cell in your body, you know those two clocks have to hit. When complexity makes knowledge
very difficult to attain, like the global recession,
like global warming, like picking out milk, right? How many of you think
cow’s milk is good for you? Raise your hand. Nobody? Nobody drinks cow’s milk? Well, it’s amazing, because there’s 22 types
of milk at Safeway. 1%, 2%, non-fat, I don’t really know
all the differences there. Acidophilus, lactose intolerant,
soymilk – which is really soy juice, there’s no milk coming from soy. But you wouldn’t put juice on your cereal. Almond milk – interesting concept. OK, we are an organism – when facts drop off,
we switch over to beliefs. We just have this automatic governor. Think about the human organism
as having two baskets. One basket is facts, gravity is a fact. The speed of light, a fact. I drop my keys – every time they fall to the ground,
never once in suspended animation. But when we don’t have facts,
or we can’t grasp the facts, we switch over to unproven beliefs. Does anybody know who this is? (Laughter) All those people that handed
their money to Bernie Madoff, they were very sophisticated investors. Make no mistake,
they weren’t people like me that have 100 bucks in the bank. These were very sophisticated investors, and they said, “The financial market’s
just gotten too complicated. I don’t know how to invest my money. Here it all is. Here’s the dump truck, you take it.” And we all know what happened,
we follow false prophets. Public policy becomes shaped
by irrational beliefs. When you’re not developing
public policy based on facts, what are you basing them on? You’re basing them on beliefs. And so you hear politicians
say things like, “I don’t believe in global warming.” Or “I don’t believe
the deficit is that dangerous.” “I don’t believe social security
is going broke.” Let me give you an example, one example going back
to ancient history, the Mayan civilization. You think early period
of the Mayan civilization, when they were thriving,
they nurtured both beliefs and facts, they were building massive reservoirs
and underground cisterns. Because, for 3,000 years, they’d had
a tenuous relationship with rainfall, and they knew that would do them in. So, they practiced crop rotation,
water conservation. They stored food
in the underground cisterns so that they’d have food
during times of drought. But as the drought got worse and they couldn’t understand
climate change – the facts weren’t available and they might not have
understood them even if they were – what did they wind up doing? They wound up abandoning
man-made rational methods and relying exclusively on fetishism. So, what did they do? At first, they were sacrificing
captured slaves to get rid of the drought. That didn’t work so well.
They said, “We’ll get our own people.” So they started sacrificing
their own people. And when the drought was at its worst,
there’s evidence for 1,000 years they were building no more
rational reservoirs, cisterns, and so on. They were relying exclusively
on murdering newborn, unspoiled infants as a solution to their drought. If you live here in California,
you know we have a similar situation. With all the resources,
technology, data, and will, we have failed to put
a meaninful decel program together. Do you think that we might have
something in common with the Mayans? What happens is we become gridlocked, we can’t understand the problem, and the second thing that happens to us is we begin substituting
facts with beliefs, and we don’t know the difference. So how do we break the cycle? Here’s the fun part. Now it gets good! OK, neuroscientists are discovering
a third form of problem solving that is evolving in the human brain. They’re calling it “insight.” Every one of you has had an insight. Think about this, this is amazing! For the first time in human history, we could put a skull cap on your head and administer increasingly
difficult problems and watch what your brain’s
doing – it’s really fun! I go up to UCS, I’m kind of a brain junky, I like to look at pictures and see
what parts of the brain are lighting up. And we’ve discovered
that every now and again, your brain starts shutting down
a variety of functions as though it’s storing up … and bam! you have an insight; it’s spontaneous,
it comes on like a freight train, and you can’t trace it
to any series of steps. And it’s always right, it’s a process by which you’ve connected
two pieces of data that were floating around
in your head somewhere, and you came up
with a very elegant solution. There is a lot I could say about insights, but I’m going to tell you
the most important thing about an insight: We have discovered
that about 300 milliseconds before you’re ready to have an insight, a small part of the brain
lights up, called the ASTG. And if you know anything about science, you know when you get to a point
where you can predict an event, you are on to something. So, what am I doing? I’m trying to get
as many insights as I can. I get up every morning,
and I do all the things I can to arm my brain, because when you don’t arm
your brain, you fall into beliefs, and you follow false prophets
like maybe some of the candidates – I don’t want to name any names for 2012 because they might be listening. I love you all, please come
on my radio program. (Laughter) So, to sum up, what am I saying? A thriving society
has left and right brain. Solving problems – that’s what we’ve evolved,
that’s what we’ve perfected. Eventually, we hit a cognitive threshold, we go into gridlock, our problems persist, and eventually we collapse
and we regenerate. But there is a way out,
evolution’s gift: insight. And neuroscience is a way to get us there. So now I want to talk
to you about mitigation. Normally I give this talk,
it’s two hours long. The big challenge at [TEDx]
is to get it down into 12 minutes, and I’m already two over. So, the next thing is the big hook comes, and you’ll be kind. Remember? You’ll be kind. While we’re waiting around
and using brain fitness, what can we do? I’m going to tell you one thing
before we get to mitigation. I am a big believer in brain fitness by a fellow by the name
of Dr. Michael Merzenich, who should be here at [TEDx] next year
and you should hear what he has to say. He’s a neuroscientist,
and he’s developed a series of programs that helps warm the brain up
before it has to make a critical decision or load content or data. In our particular case, we did a study
of 23,000 schoolchildren. We gave them 10-15 minutes
of brain fitness videos and games to play, to warm their brain up
just before they started school. Now, four years later, those children
have twice the academic achievement as kids who didn’t warm their brain up
before the beginning of school. If you think about it,
you wouldn’t run a marathon without stretching, hydrating,
and preparing yourself. Anything short of giving children
brain fitness before they go to school is, in my opinion, child abuse. If you and I are having a hard time keeping up with stuff and learning stuff
and getting to the bottom of things, imagine what it’s like
for a child in school right now. And if we didn’t raise teacher’s salaries,
if we didn’t make classrooms smaller, if we did nothing else
but gave them brain fitness, we would have a massive
improvement in education. And I feel very bad
that that is not on the docket for any educational reformer right now. And it should be
because it’s physically demonstrable. OK. So while we’re waiting
for our brains to catch up, we could arm it with brain fitness,
we can eat better, we can exercise. By the way, blood flow is idea flow. I hate to get back to exercise,
because I hate exercise. I hate it and we keep getting back
to food and exercise. And, you know, I can’t get away from it, I got to get back into the gym. OK, so what can we do
in the interim? Mitigation. Mitigation is the key to buy time,
it’s not a solution. We need to be sure we understand that when we evoke mitigation,
we are not solving the problem. So, when people ask me
what we can do in the interim, one of the definitions of complexity is that there are more wrong solutions
than there are right ones, and the number of wrong ones
are exponentially growing. So we become bad pickers of the solution. But thankfully, we have fantastic models
for high-failure rates. Everybody aware of venture capital? You might think
that they’re great success stories, but they’re actually experts at failure. For every 100 companies
that they do diligence on and invest, they’re only expecting
maybe 15 to do well. But those successes
will dwarf the failures. When we come up against a problem
like the Gulf oil spill, we have to go at it
like a venture capitalist. We’re bad pickers. But instead, what did we do? First, we got
all the smart people together and we dropped a concrete box on the hole. Does everybody remember this? Then every night we watched
the oil spewing out, and we said, “That’s not working!” And 30 days later they said,
“Yep, that didn’t work, alright. Our next plan, plan two,
is we’re going to drill from the side and we’re going relieve
some of the pressure.” And 30 days later,
“Nah! That’s not working!” Fortunately for us,
solution number three was “static kill.” But imagine for a moment
if that had been solution number 87. We would still be watching those horrific scenes
on the Gulf Coast now. So, the gap between evolution
and complexity can be bridged, that’s good news. For the first time in human history, for the first time since man
has walked the planet, we can mitigate to buy time
by using high failure rate models, and we can develop insight. What we need now is an agency like NASA,
that was developed to explore outer space, we need an agency to explore inner space. Thank you so much for your time today. (Applause)

100 thoughts on “The greatest discovery you never heard of | Rebecca Costa | TEDxSantaCruz

  1. This talk IS NOT about global warming. It is about humans reaching their intellectual maximum and how to cope with our modern issues in light of this.

  2. Climate change hhas, is, will always be happening, its just not as anthropogenic as "they"- who want to impose a tax on your very existence; think georgia guidestones- say it is. Anthropogenic "global warming" is an outright lie.

  3. If I had any doubt of the validity of her premise, it disappeared when I saw the number of respondents, rooted in beliefs, who were threatened by her presentation.

  4. She lost me at 1.5 Billion data points, because I happen to know that those data points support skepticism more than the theory that man is driving the climate, or that we can adjust it. Further it is going in a good direction, if we COULD adjust it, we could do no better than mother nature at this point in time. I am very familiar with educated morons, here is one. No offense, nice lady, but she is not smart enough to coach me or anybody else. She is repeating things that are not true, because they are popularly believed and politically acceptable. We are in a normal cycle and going in a good direction.

  5. Is she not right in the head? She has no sense of logic or cohesive thought.
    She has a few valid facts sprinkled in here and there but they have nothing to do with reality. Also, she doesn't seem to be able to stay on point or to even make a point.
    And does she truly believe that people are going to grow more arms??

  6. I get it, BUT can you Please explain to the peeps on the amount of ICE & Warm changes EARTH has been through PRIOR to MAN stepping on this BLUE BALL? hello. Can you please let MAN have one F'n ICE & warm age before I hear all this BEACHING. For the LIBTARDS, we don't matter, we are all part of the EARTH, who the F' do Y'all think made us? hello

  7. The Little Ice Age ended around 1850. At the time, half the planet was starving. We were still on horse/camelback. Since then, we as a planet have evolved to where less than 10% of the population is starving.Tell me, is warming better or freezing? Thanks in advance.

  8. we are 5 billion years old…100 years of climate observation means nothing in the time on this planet….Thumbs Down….buy a clue…

  9. She stated that 65% of people do not believe there is climate change. Where did that Statistic come from?? I think it is untrue and thrown out to create a reason to sell her lectures. There is NO gravity !!!! The World SUCKS!!!!!! See , I can start a lecture tour with that silly simple statement and CLEAN DOWN or clean up !! Holy Hot Dawgs Batman I I genually accept the concept of being intuectually GOOFY !! and I accept the reality of nothing makes sense if you actively do not want something to make sense !! Example My brother states , " Always BE yourself ! Unless you can be Batman ! If you can be Batman ALWAYS be BATMAN !! That makes sense ! Be kind to your web footed friends because DUCK could be somebodies mother ( from a 1

    1950s popular song See how far we've come along !! The intellectually challenged elected a completely sociopathic president !! Good night

    !

  10. The problem with a national health care system is that doctors and hospitals charge too much. Medical schools are the root of the problem. They are all too greedy. Stop the greed and we will have a reasonable system.

  11. Global warming was a great scam that enriched Al Gore, among others. The fact is that plants thrive on carbon dioxide and reward us with oxygen. We are entering a genuine cooling period called a Grand Solar Minimum. You'll soon be praying for a little global warming.

  12. Living in a particular place can give insights that all the studies by Intellectuals will never factor into the theoretical model.
    The variables are too many. So it was 1987 that it was cold and no snow. 1993 it was warmer and lots of snow.
    Recently summers mild and cooler, winter is temperate rain, with little snow. This year summer was a little warmer and more snow. Less rain.
    You can't tell me we are the only factor influencing the climate.

  13. We can't solve our problems, because Vested Interests, and their apologists, like Dershowitz, will lose control over our lives.
    Abandon hope as long as money-brained people like this woman, who have bought completely into Profit Driven Everything, are making decisions, driven by bottom-line myopathy, that effect everyone else.

  14. Capitalism is a pyramid scheme.
    It is legalized Usury.
    It has rendered human beings as just another commodity.
    It has destroyed the environment and human empathy.
    It has replaced common sense and basic decency with the profit motive.
    It is a dead end.

  15. The data you quote on climate change is just manipulation. You were so certain back in 2013 and are very wrong now. Y Yes , Obama was the greatest and most accomplished liar of modern time.

  16. I wasn't able to put all her lecture in one solid piece to be understandable and coherent? It was like little bit of everthing but I still don't know what was she talking about primarily?

  17. It seems like she herself is just a bit slow on the uptake. Things are too complex for her from the start. Apparently, her research into obesity didn't afford her any help in dealing with her own. She's also a slow, droning, boring speaker.

  18. try stopping the aerosol spraying of us everyday!!!!???? your handing death to future people …end of your nice little story!!!!!

  19. It's all easy to fix but no one is stopping to think for themselves or listening to me. Learn multi function logic, look at the obvious, remember that progress done right instead of resisted makes a lot of money.

  20. Your "1.5 billion measurements of temperature since 1880" aren't telling you what science says it tells you.  Because the ancients knew that sometime around 2020*, three suns would gather and another in the south would nova.  And what they knew was necessary was a news flash: "Abandon the Motherland."  The Maya did.  And the only ones among us are doing it are the thousands of millionaires who emigrated to Australia over the past few years.  (Note: *NOT 2012 … Zoroaster said the sign of 2010 would be the Big Lie of the Son/Jupiter.)

  21. I like what she had to say overall, and I don't disagree with her but that was one of the worst Ted Talks I think I've ever listened to.

  22. Interesting take on insight. I love the questions this answer provokes. They are very complicated. I love complicated questions because it’s the only place where insight has potential for existence. If you find yourself craving insight like I do, you will naturally reside in an area of personal ignorance. Well, that is, until you experience insight, which is a phenomenal sensation of personal growth.

    It is very short lived however. Because you must continue to search deeper for a more complicated question, if you want the experience insight again. We can’t solve our problems because we ask questions that we don’t know the answer to. Complexity is the only place where insight has potential for existence.

    Insight is the reward for asking difficult questions. Difficult to you personally, not according to any standards besides turning “I don’t know” to “I totally get this”.

    Complexity makes knowledge possible to atain.

    Thanks for this video

  23. I was excited to learn about this great mystery until I watched the talk. I think her discovery was that she thinks everyone in the world is a nitwit except her.

  24. er climate temperature has not been a global thing since 1880. Climate change is a natural event, and not human made. Maybe this was what you've never heard

  25. Take all the measurements you want. Thats not the problem people have with global warming. The problem is that coming out of an ice age its natural for the earth to be getting increasingly warmer. Duh.

  26. "Insight" as described seems analogous to accessing the larger consciousness system a' la Tom Campbell's model, and yes we all do it.

  27. Climate change she says it's settled O.K. how many of those Billions of Temp measurement have been altered, Tampered with and just down right corrupted, she don't know? well thats why those of us who can still think for ourselves and do a little research are called Denyers by idiots like you|

  28. You do not separate the facts of history from the beliefs of the future. We know what happened in history, we don’t know what is going to happen in the future. When we look to the future we must invoke beliefs. There is no other rubric upon which to base actions.

  29. “ History will repeat “ The Problems
    Until we get the “ Motives “ The Key “
    “ Right” “ All Life Matters “ The
    True Motive” Truth always Need All The
    Facts plus new Facts for Truth Discernment.

  30. Methinks this woman does not know the difference between facts and beliefs. She also seems to be afflicted with a bad case of We-itis.

  31. Hey! Wake up! Astronomers say ALL our planets are warming! If you can explain how man is causing this, you're either a genius or …

  32. Software development was obviously left behind by hardware development by the mid 1990's. Despite cheerful marketing "news", high failure rates in actual developments, such as "Apps" remains steady at, just my personal opinion, 90%. The only evidence from the OS platforms about this, was a tiny news bit I think I heard, about hiring people to remove Apps that died either at the starting gate, or along the way. LOVE your "Insight". The ultimate Super Computer that I know of, is the human brain. Creativity where, what we know works, combined in different ways, might provide "A Little More Time", seems to be the best option.

  33. The method we now can take to find inner peace & insights is to Groove!! Being in the "Flow" of creating music, on a global unifying basis, provides the "faith" needed to implement evolution. This faith in our instinct of music to be rehabilitative, is a proven fact. Groovists believe in the healing power of music to be miraculously evolutionary!!

  34. Most people don't believe the reason our planet is getting warmer. Not that the planet is getting warmer.

  35. i quit after hearing your "understanding" of the global warming issue – warming? yes – but why? – CO2? – probably not – the "billions" of measurements? – only if they are done right and interpreted correctly – i suggest you struggle with you CD player a bit more before lecturing on complexity

  36. Nobody argues the fact that climate changes. It always has. The argument is over the extent human activities effect climate. The sun has both climate and weather too.
    Any 93% of scientists (or anybody else) who agree on some government sought for result excusing add-on taxes are not from the top seven percent of their class class. These are not Ayn Rand typed ideal men :The individuals ; but rather populists employing emotional argumentation rather than dry cool facts pointing to reason.
    The only effective tool any government has on curbing human climatic causes is genocide and war. The only effective tool people have is self respect thus respect for others. Then we'd all make less mess and tighten waste wisely.

  37. Solutions can be implemented in a computer model to test if they will work. High failure rates are not necessary or desirable. As an example, SpaceX has thousands of successes and only a handful of failures and have revolutionized leaving earth gravity well.

  38. @ Rebecca Costa = You have personally brought TED to its "Ultimate Lowest Point of Intellectual Babble." Seriously, what a waste of TED time.

  39. It's a pity you put climate change in here to confuse us further. Climate change fraud is now known as the biggest hoax of all time since god.

  40. The entirety of the earths temp increase is 0.8 degrees in the past 100 years, measuring it more doesn't mean the temp is increasing. Of all the really bad Ted Talks , this is one that is unwatchable.

  41. The rate of change in this world was foretold 500 years before Christ The prophet Daniel said Dan_12:4  But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased. We are at the time of the end before Christ comes again to Judge the earth and its people. Things are going to get a lot worse before he returns. The word of God is faithful, but the words of of people of this world are lies. Evolution lady is a lie. The Word of God (Jesus the messiah spoke this world into being)

  42. Stupidly misframing data. Reasonable people know and understand that the climate is not changing! It is doing what it has been doing for the past 25,000 years which is warming up. Look up Holocene Era, the Great Blue Hole (Belize), Doggerland, the Aleutian Land Bridge and a bunch of other stuff. What they are saying is that the Earth is naturally warming and there is nothing we can do about this natural process except deal with it. Destroying the US economy and putting us back to the hunter -gathering level of society will kill off the vast majority of the population because they would die of starvation due to curtailing modern farming methods and the ability to transport food to non agrarian population centers, lack of medical treatment, pestilence and other horrors. Reducing the US to a bunch of hippie communes would only slow the warming insignificantly. Such actions would be useless because India, China, South and Central America and Africa won't join in. I guarantee the people who are complaining the most about "climate change" now would be the first and loudest to complain when they find out the poorest and most vulnerable members of the population will suffer disproportionately or just be eradicated, not to mention their own demise.

  43. Amazing that this woman should call her talk "The greatest discovery you never heard of" and do her ENTIRE talk and never mention a word about the discovery! Is she kidding? Also you can see that she is member of the Church of Climate Change and sarcastically tells us that since 1850 there have been billions of measurements taken. Really? I really have to doubt that but even if true….so what? Does that prove anything at all? The very term Climate Change is so idiotic it is hardly worth thinking about. Yep the climate is certainly always changing…..so what? But then I understand that those in the Church of Climate Change want us all to believe that the change is happening too fast and that we will all be fried to A crisp in a few years if we don't "do something" about it. But what she doesn't say is that thousands and thousands of people are making a nice living by promoting the Church. Ah yes…..humans are an interesting group….

  44. I believe in global warming but I also believe there is nothing that can be done about it especially by politicians and government, all they want is your money.

  45. This is an 8 minute inspirational show about a treatment to help heal mental health challenges! The show also give some inspiration on friendship and the positive affects of hugging!

  46. We have also failed, in California, to create new reservoirs to store some of the multi-millions of acre feet that go into the sea during every storm. Not all of it serves any environmental purpose but the regime likes to pretend. It's an artificial system now anyway. No one knows what the environment is supposed to be like.

    Warm your brain up? How about walking to school? And what good is brain fitness without ideological training anyway? Walking to school is just too retro. It might leave kids with some understanding of their heritage. Can't have that!!!!

  47. Maybe because 1.5 billion measurements is the same as 1.5 trillion measurements. You haven't even been doing it for 200 years and you claim to be able to know and predict everything that could happen or effect the environment. Will you go as far as to say it has never been this warm in the earths history and there is no way it is a cycle?

  48. Global warming. Every planet in our solar system is heating uo. Is that because of our? Of course not. So, scientists need to stop being so selective of the truths they tell us.

    Not telling all like data is actually lying, lying by omission.

    This person has selected her reality to make her feel comfortable in her reality. Take it with a grain of salt.

    I believe in global warming, but, it is not mankind's fault. Period. Remember what I said about every planet heating up. Look it up for yourself. Easy. Verify it. Accept it. Move on.

  49. This lady has an arrogant way of getting her point across. If you don't agree with her logic, then you don't have a logical cell in your body. If you agree with what she beli are scientific facts, then you know nothing about science. If you don't do what she believes is the best preparation for the school day and let you kids play games to warm up their brains before hopping on the school bus ? You're committing child abuse. An absolute egotist, and not very bright.
