I doubt Tom's over-enthusiastic endorsement of anti- oxidants is going to lead anyone to forgo some of their decompression obligations in favour of bulk vitamins. Especially the divers you profile (fat, hungover, short- winded, and breaching like beluga whales). These kinds of divers probably don't give a rat's arse about their health and wellbeing. They're the ones *least* likely to be interested in more exotic health care concepts. I've been using antioxidants for years, and bulking up on them before dives ever since I read about the connection between CNS toxicity and free radicals. I notice neither John Comley nor John Crea brought it to our attention that (leaving DCI aside) antioxidants just might be useful for stalling oxygen toxicity. I wonder if their scientific discipline precludes them from speculating in public. If so, then I reckon we need people like Tom, who are willing to push a position ahead of the 'hard' evidence, otherwise there'd be no debate on any subjects involving physiology, chemistry or engineering. Either the cavers and techdiver lists are arenas for open debate and speculation including solid facts, wild notions and half-assed ideas, y'know, warts'n all, and the participants are smart enough to recognise that. Or we need to be protected from speculation until an opinion has been cleared for release by some higher authority. In which case, what's the point? rgrds billyW
