I have a body I use for business, another I keep for pleasure. A day body for staying in, a night body for going out. One for exercise, one for travel. One for cocktail parties, another for funerals. One for left-brain analysis, another for right-brain creativity. One for sleeping, a different one to practice salsa dancing. All of them self-maintain through automatic routines when I'm not using them—they still have to eat, excrete, exercise, and sleep, or they'll fall into disrepair. After all, you only get a couple dozen bodies in this life, so you should really nurture them carefully.
