If a human grows up in space, what sensations (e.g. coriolis) would they not be used to upon visiting earth? Aside from bone and muscle differences, which have already been covered. For example, someone who grows up without being spun around at 400m/s as the world spins; would they feel as if they were spinning when they set down or entered orbit?

How does the body get electrical energy from food?

In common parlance, one would say the body 'burns' food, and, indeed, we are warm creatures due to some kind of exothermic reaction(s) inside us, yet our muscles and brain work on electrical impulse. Is this the most efficient conversion of heat to useful energy we know of, or is the electrical energy converted from chemical potential energy somewhere?

Tailbone trouble? I was studying anatomy in school but as a class we just could not get around the uselessness of the tailbone. Did we lose a tail? Is there a similar structure in other animals? Are there any other useless parts of the body?

How long is it possible to live for? As medical knowledge improves people live longer and longer. However is there something in the body that limits this? and if yes, have we reached that limit now with people living to 122 or is there more to come? Also, with the promise of "magic" stem cells and the ability to grow your own body parts, could we live for ever?
