If I have to explain it, it's no fun.
1. Find a website exposing scientology. That will cover Xenu.
2. Go peruse a supermarket tabloid. That'll take care of Katie and the
baby.

Na, he died a VERY rich man. He may have been scum, but he was
brilliant scum.
How many plans do you have for people to just give you lots of money,
AND never pay taxes on it?

Ive always admired L Ron Hubbard for continuing to write & publish long
after he died.
I admire that kind of dedication, that commitment to the craft, in an
author.

"Xenu is the father of Katie (Cruise)'s baby."

And the horribly simple facet that I dont have to suck the life out of or
take money from people I mislead to buy my dinner.

I earn what little I have and that is enough.

but it's not *solely* a function of partial pressure. It's just that
the other factors either average out, or are small compared to that.
For instance, I don't think it's unreasonable to assume that the rate of
gas transfer also depends on the area of the membrane through which the
gas must pass, which will be consistantly too small or too big if you
use lung-volume as the only method of buoyancy control.

Also, there is a question of CO2 buildup if you aren't completely
evacuating your lungs from time to time.

Who's talking about not completely evacuating your lungs from time to time?
I'm talking about taking a deeper breath from time to time and expelling it
more slowly or in the reverse, expelling quickly but fully and taking
smaller breaths. It all depends on what the intention is at the time.

Lee, where are those "statistics" listed?

Thanks,

zamatim

I don't think one can support a point by assuming anything. In particular,
I don't think you can simply assume that the surface area, in the lungs,
available for gas transfer changes as you breathe.

I also think you need to be cautious in your use of terms. The term
"lung-volume" implies it is the maximum expansion of the lungs that is the
control mechanism. While that certainly will work, it's not what we're
talking about here. We're taking about taking the same deep breath you
would otherwise take, but changing the way you take that breath to alter the
average lung related buoyancy.

Nobody ever evacuates their lungs completely, ever. Nobody even comes close
without forcing the exhale beyond what is normal and comfortable. Further,
your mention of this issue make it clear that your focused on maximum and
minimum lung volume, neither of which is involved in the changing of
breathing patterns under discussion.

You and everybody else that has not made the effort to break the habit.
Skip breathing is natural while underwater. Continuous deep breathing it
the learned skill. Skip breathing is believed to be responsible for carbon
dioxide buildup in some divers. The most commonly reported symptom that it
has become a problem is an unexplained headache.

By holding each inhale or each exhale a bit longer, some believe that they
are reducing their gas consumption. Chances are, however, that they are, in
fact, increasing it. The buildup of carbon dioxide is a breathing trigger
that can increase the breathing rate beyond what is actually necessary to
sustain the actual level of activity.
