52 and:
Still listen to metal music
Hair is still the same color as when I was young (at least on my head, we won't talk about the inability of my beard to follow suit)
Hair is still all there
Everything still works (when it wants to, not when I need it to
)
Back in college (I think I'm older then most of my teachers)
Still trying to do things that REALLY HURT the next day (like getting out of bed, breathing,etc.)
Mind is still like a steel trap (though I seem to need to lubricate it much more often
)
