TweetThe most popular answers are not surprising . . . without much hesitation - I'm assuming that all else would remain the same (no tricks or trade-offs) - I would choose to be smarter. I'm not a bad looking guy - and I'm married with 2 (almost 3) kids anyway. I could be thinner, more conditioned or bigger with more training and "supplements" as the article said. Younger . . . . well I can see choosing that one if I were 15-20+ years older than I am now - I'd do that if I were older. But I'd definitely choose to be smarter/wiser because that, in my mind, would be the most valuable quality to posess. Being smarter (how much smarter, by the way???) allows you to make better decisions, which improves your quality of life (possibly more $$$ too), gives you the liklihood of producing smarter kids who will take good care of you later in life (and you can brag about them to the other old folks), and maybe gives you the ability to influence people and situations to some degree. No question, I'd definitely want to be smarter.
