Epicness has nothing to do with age! I have mellowed over time (jail time is no longer a layover requirement), but frequently fly with A's and B's with whom I could never have keep up and still can't. I think a part of it is when or whether you got "it" out of your system. I got it out in college and early AF time. Some of these energizer bunnies don't need sleep - many don't need or want a sidekick.
