10,500 feet is way the heck up there!

I realize that. The more nitrogen you take in, the more of a problem it
is during an ascent. One breath of air, as in a free dive won't generally
cause too much trouble. Holding your breath on the way up rather than
letting the gas go as your lungs expand is another matter, pneumothorax (sp)
I believe the term is. That's not the bends though. I was referring to the 2
minute decent to 132 feet though, not a breath hold. I personally have done
that, I cannot hold my breath like that.

The trip back up is where you need to go slowly or risk the bends.
Won't happen in a free dive. This is a result of taking a breath from some
depth (as little as 4 feet down) and then not exhaling when returning to
the
surface, or staying at a certain depth for a long period of time and not
using decompression stops on the way back up :-)
