sleeping in zero gravity

What about smacking your head into something?

Well, I'd think you would be at no more than a very slow drif, so the bump should be too small to care about

Actually, I've heard that the reduction in wolves is partly to blame for the boldness of mountain lions and deer in suburban areas. It used to be those animals were familiar with wolves, and would steer clear of them. Since there are usually dogs living along with humans, they'd consider them to be wolves, too, and having learned that wolves are dangerous, they'd stay out of the area. But without wolves around to teach them to be afraid of dogs (most dogs aren't all that threatening on their own), suburbs seem like nice, safe, lightly wooded areas with lots of easily obtained food, whether you're a deer or a mountain lion.

It's possible, but I've never heard of that personally. However, Mountain Lions are also afraid of humans (I'm not sure if you knew that or not, I just didn't get the gist of that from the post). When humans work hard to nearly wipe out the Mountain Lions, they tend to realize what it means to run into a human.

is it elastic? that seems like it could give you the feeling of a "downward" force.

Not as gross as what happened in Apollo 8 : the commander had diarrhoea for a while, and the LMP and CMP had to ... erm ... assist with the clean-up.

I once sneezed into my mask while working in a clean-room, which was not a great deal of fun.
