From slehman: Now let me ask this: If you lived at 40 feet, or 80, as long as you weren’t breathing compressed gas, there’s be no limit at all correct?


I would assume that if you’re breathing air that is pressurized to 1 Atmosphere (ie: in a submarine or underwater habitat), then it shouldn’t matter what depth you’re at. Of course, as soon as you "step outside" to the increased pressure, you need to follow depth/time limits and decompression rules. Submariners are deep underwater for months at a time and do OK because the sub is pressurized to something close to 1 Atmosphere the entire time.
