How long you can stay under. It depends on a number of variables, such as, are you diving with air or a mixed gas like nitrox. Other considerations include water temperature, how deep you are, are you making a repetitive dive, etc. Diving to 60 feet using Nitrox 32, your NDL would be 100 minutes.

The limit of breath holding is dictated by how little oxygen and how much carbon dioxide you can tolerate in your body. Both of those, however, are governed in turn by your metabolic rate. A diver swimming through the ocean will use up oxygen and produce carbon dioxide faster than one lying motionless in the water.
