What about an extremely fat diver with a VO2 max of 70ml/kg, why must you
equate fat with no conditioning, and a dangerously low VO2 max? 
Also, how does all of this apply in the real world of deco? Not a 3 hour
exposure at 300', but 25 minutes at 240'? 45 minutes at 130'? 

I just feel weight has nothing to do with this discussion, however
conditioning, smoking, asthma, and other physiologically limiting conditions
do. I know plenty of fit overweight people, and I know plenty of unfit thin
people.
