What part, mine or Esat's? Mine is easy - only a dumb fuck would jack up the
oxygen to think he is beating deco an take that degree of damage and
unacceptable risk. Esat's is easy also - the chemical description of what
you are doing to yourself by jacking the oxygen.

Ever feel that weird cramping discomfort in the big muscles on a dive? Esat
is describing that process in one sentence.

Esat is a scientist who is charged with finding causes, mechanisms and
possible cures for some of the most complex acting substances in this
universe. He has long ago learned not to draw conclusions without looking at
all the moving parts. He is the absolute best at seeing things that escape
the causal observer.

I merely iterate around until I find something that works, then I ask people
like Esat and Weinke why they think it works, thus raising my own
understanding and possibly seeing paths to the next level, so to speak.

At the risk of sounding like a total moron (and getting flamed for it), can
someone translate this into something the layman can understand?

Thanks,

Politicians and diapers have one thing in common: They should both be
changed regularly and for the same reason.
