Bill Gates and the president of General Motors have met for lunch, and Bill is going on and on about computer technology. "If automotive technology had kept pace with computer technology over the past few decades, you would now be driving a V-32 instead of a V-8, and it would have a top speed of 10,000 miles per hour," says Gates. "Or you could have an economy car that weighs 30 pounds and gets a thousand miles to a gallon of gas. In either case, the sticker price  of a new car would be less than $ 50. Why haven't you guys kept up?"  The president of GM smiles and says, "Because the federal government won't let us build cars that crash four times a day."  Why is that funny (or not funny, as the ease may be)? Human beings love to laugh, and the average adult laughs 17 times a day. Humans love to laugh so much that there are actually industries built around laughter. Jokes, siteoms and comedies are all designed to get us laughing, because laughing feels good. For us it seems so natural, but the funny thing is that humans are the only species that laughs. Laughter is actually a complex response that involves many of the same skills used in solving problems.  Laughter is a great thing--that's why we've all heard the saying, "Laughter is the best medicine." There is strong evidence that laughter can actually improve health and help fight disease. When we look at laughter--what it is, what happens in our brains when we laugh, what makes us laugh and how it can make us healthier and happier, there's a huge amount about it that no one understands yet. Which of the following is true according to the passage?
Humans laugh because of jokes, sitcoms and comedies. Humans laugh because it can fight disease. Humans have gained skills to laugh since they are born. Laughter is a complex response of humans.
