Like Tom Prince and the "line". 
when i'm young, i'm all insecure and shit.
now that i'm pushing 37, you know... hey, you loosen up a bit. you realize this, today, is probably the best you'll ever look + fuck + feel at the same time. Nobody hits 57 and says "Wow, my muscle, penis, brain work SO much better now than they did 20 years ago."
So use it or lose it, I guess. Hit that shit, get a grilled chicken sandwich with a smoothie on the way home, and catch the 1am replay of Fargo on FX Network. life is good.
