I'm 55, somedays I feel like a kid and sometimes I feel like sh*t. the general consensus is that most people are over the hill at 40. I never felt old old until my mid-to-late 40's, at that point I was not "interesting" to the ladies in their 20's any longer. I was flirting and not getting "flirted" back. I generally looked and acted 10 years younger than I was, but there comes a point when you don't look 10 yrs younger anymore. I still look good for my age, but my face and neck show my age. most people guess I'm 51, 52 yo.
