Two heads are better than one, but two brains in one is better still. Why spend a whole semester studying for some tedious calculus final, when a quick injection of properly coded RNA can make you a whiz kid overnight.

    There are basically three ways to get oneself out of a real tight spot - lawyers, guns or money.  You want to keep the third for yourself, and even you lack the stomach to transport the first, but you're happy to supply firearms to the truly needy, provided they can meet your price, of course.
 
 

    Left your heart in Anhur?  No problem, just order up a nice fresh replacement from Hephaestus.  (Unfortunately, your cargo pilot is generally not included when selling of a load of fresh organs.  And be warned - the Teamster's Union gets downright nasty if you even joke about it.)

    The world's oldest profession has transmogrified itself into one of the world's most lucrative industries.  A mid-range Pleasure Borg can provide any service available from a traditional professional, and when it's not working it can be turned off, disassembled and kept in a convenient, semi portable carton. Incidental upkeep is significantly less, by comparison.
