Except when you realize that your life isn't much fun without work, work, work. I have friends who travel. They love it. For me: Been there, done that. I have friends who like to sit around their homes reading, eating, watching TV, sleeping. Yeah, I've done that, too. It drives me goofy, after a while. I like the physicality of the work I like to do. I fully understand that my body will slow down, eventually. Eventually, my mind may want to do those things my body can no longer do. I'll deal with that when that time comes.
