I initialy thouht it was a great idea - you can clone yourself and leave all your worldly posesstions to you in your will - thats not gonna go down well with your family mind!
You could even grow a mindless nonsentient 'you' and use the organs for future transplants! Cool.
Go even further and you could have 'internal cosmetic surgery' - just like we do today on the outside!
This my friends is the next stage in human evolution - this will happen. Only problem being you will have a bunch of rich superhumans in America, Asia, Western Europe, and then you will have Africa. That my friends will be a travesty.
