Two points. Both being argued from experience. Both, from the arguers perspective, are correct.
So would you have us go back to the days where only super fit military style men dove and the rest sat in fear of the water or unable to dive because they couldn't pass the physical aspect of training?

And i am not saying this to attack overweight or smoking people. But they dont belong in the water IMHO. If someone that is overweight and or smokes manages to be in topcondition by rigorous training, fine, but if they are not they are a liability. And if you are a non-smoker and have a perfect body, great, but only if you are in good shape. The underwaterworld is unforgiving and dangerous.
