Cool, thanks everyone (so far, pls keep any more opinions coming).

I'm finding this very interesting. On Rebeather World the vast majority of responses were "hell yeah, spot on" ie. they were all for having witch hunts, and never diving again with people who don't fit their version of healthy people. And they didn't even define what that meant! It was a little un-nerving.

My opinion is that, yes, you should be fit and healthy for the type of diving you're doing. So if you are not regularly diving in a 3knt current and doing 4 hrs of deco, then there is no need to run marathons on the weekend.

So I am glad to see here that everyone thought about their answers a hell of a lot more thought than just posting 'hell yeah'.

I guess you've got a different sample on RBW - it's interesting reading about the incident on SB, and how it panned out, what happened and what people think.

There's two school's of speculation - either the guy had a cardiac arrest, or he overbreathed the unit and suffered from the effects of hypercapnia. I would assume that CCR divers are more focused on the risks of CCR diving, where as those of us who dive OC have got a different baseline on which to form an opinion?

See above! Maybe CCR diving just has a different set of risks and the guy should have been running marathons on the weekend!?

I've been desperately trying to not add my opinion but alas I am unable...

Unless you are an independent instructor you are most likely not in a position to fail a student if you don't think they are up to scratch. Failed students= Lost profits for the shop. You may think that to be cynical and that's your right but it is also IMHO the reality of it.

Fitness? sheesh that's a nasty one to bring up round (no pun intended) divers.. I've had a rollercoaster year with fitness, with a foot then a knee injury (both work related), going from running about 40-60 kms per week offroad to suddenly next to nothing for 5 months and gaining 10kgs.. Back to running now and the thought of ever going through a spell of relative inactivity like that again fills me with dread (still was diving on a weekly basis but not getting the heartrate up). If you don't get at least a half hours excercise a day (half hour sweating with heartrate about 70-80% of maximal) then you really are setting yourself up for some nasty sh!t down the road, seriously there is no good reason if you are mobile to not get fit. We live in what is probably the best country in the world for getting out in it and getting fit.

Good on you Tara for having the guts to have a word with divers on the larger side, You can kill people with politeness.....

Not wanting to drag this off topic, but that's a fairly major generalisation.

Most instructors will never *fail* a student ever - but they will suggest that a student needs more time before finishing a course. There are plenty of shops around that actively encourage their instructors to push students back to the next course to give them that time. In my experience, having a discussion with a student along this lines is normally greeted by relief - the students know they are not ready, and and are apprehensive about continuing with the course. It's actually good for business to give them the extra time - they are more likely to carry on diving if they finish their course comfortably.

I'm not saying that there aren't shops like you describe, Rob... but they are not all like that. Certainly the shops that I've been involved with in NZ are very supportive of instructors who say that a student needs more time.

as well as the students knowing it to be true and actually asking for more help/time/training prior to open water.

No probs - I have what I want from the thread now :D

I agree, that's why I thought this might be an interesting thread/discussion. Actually, I'd extend this - Forget diving, it's a tough conversation to have with any westerner these days! Everyone know what is good for you, but how many actually do it? Why is it getting less and less acceptable to smoke, but it's ok to feed your kids a can of V and a pie for breakfast?

Oh :shock: . I just assumed you were a tubby barstard all your life :wink:

Well said. I have some nasty family history in the heart and bones area (my Dad had a triple by-pass, and a hip replacement all before his 50th birthday), so I am somewhat tunned into what could happen if I don't look after myself. I have thought long and hard about the impact it would have on my Mother and the rest of my family if my Dad passed away, and as a result I like to think I take my obligation to stay fit and healthy pretty seriously.

Well if you're not allowed to smack the little shytes then you have to hurt em in other ways.. :twisted:

I think it may have been partly because my body is such a finely tuned machine that I put on the extra kgs temporarily.. Subconsciously I saw the possible hard times approaching and my body laid in stores but now the recession is lifting they're going again.. :D

Yup diving is an unforgiving hobby for medical events whilst submerged..

Nothing like Pies!
Cuz I can't cook...
x3 meat pies in the nuke oven with a "beep-beep-ping" and "wallah!"
Then scramble pies with a mix of choice sauces and a light sprinkle of parmesan cheese. :mrgreen:
Just drifting along with whatever is current.
