- Maybe I was little inaccurate. Of course the effect is same in the chamber
- as in the water. I just meant psychological difference to notice this.
- In the chamber, there is nothing else to do but to observe, so it is easier
- to notice little things like this. In water, you have to consentrate to
- your task and surviving. Reason that I haven't noticed this effect while
- diving is probably that I haven't payed enough attention to it. Also in
- water, you can not say that is the increased breathing load due to regu-
- lator or pressure itself.
