How long can I last under water?

What causes snorkeling deaths?
Preliminary data from a study released last week suggested that oxygen deprivation induced by rapid onset pulmonary edema, known as ROPE, is the most probable cause of snorkel-related fatal and near-fatal drownings. Drowning by ROPE is different in that a person doesn’t necessarily have to be inhaling water.
