Ah ah, anyway, this would be pointless if it makes you far more likely to reach death before having a chance to have kids. I guess it would be an optimization problem.
Maybe a guy takes caffeine because he's stressed about his financial security and can't sleep well, and the caffeine prevents him later from sleeping well at night propagating a vicious circle => worse babies.
