This is all bullshit, I had knee surgury after Christmas ( 29th) and did a deep cave dive with a 100 minute bottom time on New Year's day. I was still on crutches when I did the dive. I dropped 225 pounds on my chest in a rep contest with some of the bros at the gym ( blacked out) and broke those bones in the front, and dove right through it with zero waiting time. Based on the fact that I had no pain yesterday with considerably more weight, I did no damage by diving. Anything from DAN is one step below what you could learn from a parrot or a minah bird. "Alert Diver" magazine is in fact the Bible of the Boat Monkey, and I have yet to see anything out of these guys that does not come off like Harvard Lampoon when you read it. The one good thing about diving and the human body is that diving makes the body think it is suffering trauma, and that it is under attack. This causes a huge cascade of defense and repair machanisms that end up being the equivalant of about $1000 worth of geneticly engineered hormonal drugs each dive. If you are well vascularized and perfused, this is like taking a special DNA/RNA level treatment that lasts for days. Combine that with the right deco and gas choices, and you end up ahead of where you were before you dove. If you are not in good shape, it ends up causing more problems and screwing you over completely, since the defense actually sets up the dcs, and then you need the hormone releases just to get back to even, which never happens due to the nature of the damage caused by the shunting and angiogenisis around the shunts that sets up. At least your fingernails get longer. Antonia Barnhart wrote: > > I would like to know why you recommend waiting three months after eye > surgery before resuming diving.
