Of course not, which was Hugh's original point. For someone with your
diving experience, bioactive body mass is a three sigma factor in air
comsumption. You use a lot of air because you're overly excited, you
thrash about much more than necessary and, in general, you don't know
what you're doing (kind of like the teenage boy. Do you get it now?).

Actually, I don't use a lot of air. As I mentioned earlier, my dive
buddy last Thursday said we used about the same amount of air. We are
also close to the same size with him being taller. I have more muscle
mass but he has more than normal from being the martial artist, I
presume. But, that is beside the point as your analogy is not even
close to what I asked of Lee.


Your instructor, a veteran of many, many egos like you, agrees with you
that muscle bound guys use a lot of air because it shuts you up and is
much easier for you to swallow than the truth (he's also veteran enough
to know that business comes first, and if bruises your ego too much you
won't spend money in his shop). We, who have no such commercial
restraints, and who enjoy popping overinflated egos, simply point out
the truth (and have a damn good time doing it :-).

See, you again know nothing in which you speak of. He was addressing
the class and mentioned air consumption and how women and small people
tend to use less air and that large men and those with a lot of muscle
mass tend to use more air...as well as smokers. It was basically a
lecture after returning from the pool on the last day. Nobody in the
class mentioned it nor did they pose any question.


As for the weight/mass thing you're saying, or at least implying, that
because you measure your dumbbells in a unit of mass instead of a unit
of weight (or to be more correct, a unit of force), you somehow negate
differences in "a" (for f=ma). The last time I checked, the sport was
called "weightlifting" instead of "masslifting" for a good reason.

I don't compete in weightlifting, dumbfuck. I compete in
powerlifting. It just goes to again prove that you have no reading
comprehension whatsoever.
