In either case, the sticker price (标价) of a new car would be less than $50.

Jokes, sitcoms 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.1.
