Dudes stay hot longer these days.Thirty years ago, George Clooney and Brad Pitt would have just been a couple of old dudes. Well, maybe not them, because gosh they're cute, but the average 49-year-old man for sure wouldn't have garnered much attention from young women.

That's because men are being considered attractive for a decade longer now than they were 30 years ago. That's right, fellas. Just call us Generation Generous.

These days, a man's got until the age of 55 before we stop thinking of him as "hot" and start wondering whether to buy him Werther's Originals or a nice box of steel cut oats for Christmas. Researchers credited the shift to increased expectations guys feel to stay physically fit and dress well, along with the fact that more women say baldness and a paunch aren't necessarily deal-breakers. The study polled 1,000 men and 1,000 women age 18–60.

So, this must explain why we always see so many young, beautiful women out with older men. We were sort of puzzled before.
