I've always enjoyed living my life like I never aged beyond 35 or so.
I keep my hair long - very little grey so far. Wear hip clothes. I hate wearing a suit. I keep saying the next time anyone sees me in a suit I'll be in a box with my hands folded on my chest. Still own a pair of Jesus sandals from the late 60's. Wear my cowboy boots when its 98 degrees out.
Think young. Feel young.

And then....
One day you wake up & your arthritis reminds you cold weather is bad. Can't have too much coffee - BP gets too hi. Gotta give up smoking. I'd give $50,000 to be able to pee when I want to.
I won't even go into sex. It's a real "touchy" subject...
