Some people are more concerned about appearances than others, but at
your age, it IS a hard idea to wrap
your brain around, getting older.
I'm 41, and I feel no differently inside than I did in my early 20's. Time hasn't been overly kind to me in some respects, and yes, sometimes, that's a bit tough to deal with. But, as you age, other things will become more important. And, hey, some people maintain their youthful looks wonderfully.
