I don't know about bad family histories but at least for smoking the DIR folks (GUE) already do. Is that absurd? In fact...with a rather limited understanding of that philosophy I thought that that was extended in principle to any "unnecessary" risk. It's one of the things that I originally had a problem with GUE over (then being a smoker myself and therefore excluded from what I perceived to be their "club"), but worked through to understand! (for the record....I WAS a smoker and actually gave up about 8 months ago now.) How can something that can be detrimental to peoples safety ever be absurd? Further......how can a buddy pair, or even a DIR team, ever be solidly founded if it's relying on the fact:TSandM:you really should extend that argument to smokers and people with bad family histories as well. It starts to get absurd very quickly.
"he's not terribly worried about it, since we almost always dive where there are lots of other people"?
I'm not getting personal here....it's just a good example of justification that we all seem to make. Let's face it...people are REALLY good at underestimating stuff that they don't want to accept if it's going to cause them to have to either make a serious change to, or give up completely, when it's what they want to do. I do it....you do it...we all do it.
