It's a good idea to keep a table and a wrist calculator when scuba diving anyway, in case you're subject to nitrogen narcosis, which makes you really stupid.

Nonsense. It's a good idea to not do stupid things like breathing narcotic mixes at significant depths.

  Did you actually dive at sea? You may feel the narcosis at varying depths, depending upon the temperature, your fatigue and some other parameters. You may usually dive at 50m breathing ordinary air without problem, and some other day get completely stoned at 40m. This happens sometimes, particularly when you dive for the first time after the winter break for instance.

    I was diving at sea last weekend. I don't dive air at 40m. Your other comments about narcosis are sheer nonsense, completely off base. Don't breathe narcotic mixes.

      > I was diving at sea last weekend. I don't dive air at 40m. Good for you. In France, you're allowed breathe air down to 60m. Most people commonly breathe air down to 40/50m, or did so recently enough. > Your other comments about narcosis are sheer nonsense, completely off base. Don't breathe narcotic mixes. My oh so numerous comments about narcosis? What are you talking about? Instead of giving condescending lessons, would mind explain what you mean?

        I don't care what's "allowed" or not. Where I dive there are no scuba police to tell you how deep you can go or what gasses to breathe. There is no evidence that most divers breathe air down to 50m. What you subjectively "feel" about narcosis has little relevance to what's actually happening in your body or how impaired you are. As for your comment about feeling "stoned" the first time diving after a break you seem to be implying that divers can somehow adapt to narcosis over time, which of course is completely wrong. http://www.us.elsevierhealth.com/product.jsp?sid=EHS_US_BS-SPE-954&isbn=9780702025716&lid=EHS_US_BS-DIS-1&iid=null http://www.us.elsevierhealth.com/product.jsp?sid=EHS_US_BS-S... I am being condescending because you are posting dangerous misinformation in a public forum. Divers who believe those lies and fairy tales tend to end up hurt. If you don't know what you're talking about then it's better not to post at all.

On the other hand, they go to wikipedia, where you should have a look.
