the hypoxic drive (the stimulus to breath being low O2 levels) is only seen in people with COPD or bronchitis and people with respiratory diseases/problems. the regular stimulus to breathe for everyone without these problems is high CO2 levels, not just those wishing to hold their breath longer.
edit: i just read one of your aforementioned posts and it appears you already covered this. oops. my version may be easier to understand though.

that's because when i get someone at the gym walking up to me and asking me training and nutrition advice, i don't attempt to confuse them or make it excessively wordy. i give them my advice very straight forwardly and simply with tid bits of my personal experience included. when you get all in to your myofibular gibilty goop no knows what the hell you're saying. you think some kid in college who wants to put on a few pounds needs to know that? :ranter:
