Yea, sometimes I feel like a 40 year old guy trapped in a 76 year old body. Sometimes I look in the mirror and ask "Who the hell is that old coot and how did he get in my house?"You're only old if you think of yourself as old....I'm 72 and I can't work as long or as hard as I did a few years back, I get out of breath quicker doing manual labor, the knees ache after standing at the lathe for a few hours, takes me longer to pee than it used to, but in my head I'm still a young man and plan to stay that way....
