But diving is not like CPR. CPR training trains you to work directly on another person who is at the edge of death. Diving is more like baseball, bowling or golf. I do it if I feel like it.
Actually, the person
is dead. At the point a rescuer is intervening with CPR they are doing nothing more than keeping tissues alive until further intervention can be brought in (def device such as an AED or Paramedics with a defib) or it is determined that the individual is beyond recovery (blood settling, rigormoritis setting in, etc..). The reason why the card expires every two years is that individuals, whether regular person on the street or trained medical professional, get rusty on their skills and sometimes the information gets outdated.
It's been suggested that with the CPR cert, folks have to take it 4 times before the concepts and information starts to really sink in and make sense. I believe it... I'm an instructor, rode on ambulances, even done CPR on people experiencing a myocardial infarction and I had something new click this past Re-Up.
Now, something to consider.. if I hand't found SB and had a place to chat about ideas, skills, meet others and dive in person and chat, etc., and I was relying upon the dive shop and meeting folks out and about... well, lets say that my dive learning curve would have stopped a few years ago.
Like I mentioned earlier, it really doesn't bother me that much though. I have a few guidelines I stay within for new buddies, boats, etc., and just enjoy what dives I'm able to do when they come up. I've met a lot of good divers who enjoy the same dives I do and its not real tough to hook up or get a group together to terrorize some local ecological system with our presence.
