wallowing and endorphins

Isn't wallow a great word? I love wallow. It not only can be used to describe so many feelings and emotions, but also it conjures up a fantastic image of a herd of hippos moving around in a vast expanse of mud. Maybe it's just me, but I always get really excited when I can tell people how much I am wallowing in my daily life. You can wallow in self-pity, anger, sadness, happiness, and in homework. I frequently wallow in endorphins after I complete a tough cross-country or track race. It's so much fun. That's another thing. Endorphins, how cool are they. I mean if you ask many runners why they run, part of their answer will be because of the great feeling you get afterwards. I think it is super cool that the human body came up with a way to release these "happy" chemicals after basically trying to beat you over head with muscle exhaustion and aerobic death. Apparently the body rewards you for almost causing it to collapse from heat stroke!
