60 and Over
.... and that is Dempsey who is 60. I'm not trying to knock down your argument as I think you are correct, probably just used the wrong sample size! lol Many women think I look great for being over 60 myself! Even though I don't have silver hair. 
Bald is the new silver!!! 
Oh! you are right, the pool is not correct. I did not want to mention Brad Pit and/or George Clooney because they have been handsome since they were young. The particularity with Patrick Dempsey is that he was NOT that attractive as a young actor, only after turning 40 he got very, very good looking and sexy. Now, Jon Hamm (Apple's Your friends and neighbors) went under the same evolution (he's one of my favorites ) with his retro-handsome look. Oh! Robert Downey Jr. that is another super handsome man. Anyway, needless to say men 60+ are sexy, and hot.
