You deep air divers often suffer significant neurological damage which probably explains your inability to think rationally or communicate effectively. However, we welcome your presence on these lists as a stern warning to others of the dangers of repeated deep air diving. You are obviously having a bad day. Possibly, the nurse who fed you your breakfast was in a hurry, your diaper is full, and the effort of pecking out messages on the keyboard with a stick strapped to your forehead is exhausting you. So allow me to step in and translate for you. >First I don't see any need for deep stops for such a reasonnable profile, >and in >general almost any air profile except the most extreme way beyond the >maximum PPO2 recommendations.

Such a lack of >skill represents some risk on air, and a serious one on O2. Translation: "I think people who are not good divers can deco dive as long as they compromise their choice of deco gasses to compensate for their inability to dive. I think also that the nurse who fed me breakfast this morning was unecessarily impatient." >I know only >strokes use 80%, but I think it would be much safer in this case, >although I would use 50% myself for more versatility, at the expense of some >more minutes underwater. Translation: "I think it is safer being a stroke. In fact, getting a neurological hit from being a stroke, is a lot like having a stroke. You get to sit in a wheel chair, pee through a tube and and other people look after you. For example, I have mashed banana in my hair from breakfast and will require assistance to remove it, but the nurse will be along soon. I expect." > >Third for such a profile plan your dive on whatever software you want, so >you know what to expect.

Translation "Nobody ever got bent from blindly trusting their computers. Take me for example. I'm not really bent. I just don't feel like moving my arms and legs that's all. Besides, any minute now, the nurse will be along to get the banana out of my hair. You watch." >Fourth proper deep air training answers those questions, teaches how to >chose the last deco depth depending on the conditions, mow to respect >closely your >planned deco depth through the use of proper gear and procedures, etc... Translation: "There are places where you can get training to dive deep on air. You should do the training, becuase as brain damage mounts and your cognitive processes diminish, you need repetitive muscle training to function." You also learn the use of proper gear and procedures, like the wheelchair, the bedlift, the catheter and the emergency buzzer. some people can also learn to eat breakfast without getting mashed banana stuck in their hair. I wish I'd learned that." >See >my point?
