Do you smoke?

2) Young people usually don't have serious reasons to smoke, and they don't smoke because it's cool (the brain has evolved and is no longer susceptible to such things), but because it's boring to stand with smoking people when you don't smoke yourself, so it primarily depends on the people around you (again, I'm friends with other non-smokers, so there's no incentive to smoke). It's a bit convoluted, but the point is clear.
