Money. No more working at the office, and I have all the time in the world to find what I actually like to do.

Science fiction stories coming true. It feels like we live in the future.

What about never-ending teeth? :) One falls out another grows in its place... That would be nice.

Male vs. female stereotypes. Clothing, behaviour, values - every culture has its own sets for men and women, and punishes you (more or less severely) if you do not conform.

The major fault, I think, is body's inability to communicate clearly with conscious mind. I'm not sure whether it's body's or mind's fault though.

But just imagine your body reporting its status clearly:

- illnesses, blood clots and tumors reported at the very start, when they are easier to heal

- nutrition requirements, even in the form of "which foods do I need today"

- overheating and lack of hydration reported long before you faint from it

- when exercising, knowing the optimal program your body needs today

- stress levels report

People would be much healthier, if we had this constant, clear, immediate feedback.

And why two sets? You grow one set of teeth, then they fall out and another set grows in its place - and that's it?

It's not that we have no ability to regenerate. Small cuts on our skin regenerate perfectly. We just need much more of it.
