Well, I do not know about the others, but Bill Mee is a biomedical engineer. The rest who have brought this up are MD's. The others we hear it from are human cell biologists, and those who continue to fight it are deep air instructors with zero education who are desparately fighting to continue to take money from the suckers to dive deep air. You tell me who has it right, J.O. Between the deep air morons and the general morons who do not yet want to admit that PFO exists, the lawyers are going to milk a few insurance companies like cows down the road someplace until the sutpidity is blasted out of dive intstruction, and responsible attempts are made to inform potential divers of the real risks of diving. The only real impediment to this is the false belief that previous ignorance will result in lawsuits, and the real problem that the farm animal stupid fleet of instructors out there will have to try to explain something they are not capable of understanding, my complaint with dive instruction all along. nelson wrote: > > Ben Greenhouse wrote: > > > > Nelson; > > > > "One" never claimed to be an expert, my rationale behind that > > thought was that the blood would become more viscous due to the > > increased rigidity of the RBCs.
