Hell, I'm 25 and Scott's at the top of my "hot" list as of recent, I'd take him. He works out so I don't think he's fat, if you really look at him he looks more toned than flabby.
I know people my age who are so "old" in their minds, they complain how ancient they are and it's really annoying. Then, you'll have awesome people in their 60s who look fit and love life. It's all a mental thing, you're as old as you think you are. I mean, Mick Jagger looks beyond death and I read that during a RS show it's like he's running 12 miles or something. If he can still wear tiny tees,sparkly belts, and get women to throw their underwear at him at 60+, surely Scott's got many more years of "rock" ahead of him.
Paul McCartney just turned 68 today and I'm seeing him in August, almost 3 hour shows he does.
