Do you like scuba diving? I always enjoy breathing under water.
I have only done it once, but yes it is exciting! I would love to do it more often to see and explore some cool places.
I prefer the open circuit scuba system due to the discharge.
I could see the benefit in that, the scuba systems all vary in some way or another
I would love to do freedive but I do not need to hunt for food.
Freedive sounds like it would be interesting. Diving can be dangerous though, so safety should be a priority.
Freediving blackout
Freediving blackout, breath-hold blackout or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold (freedive or dynamic apnea) dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it. It can be provoked by hyperventilating just before a dive, or as a consequence of the pressure reduction on ascent, or a combination of these. Victims are often
supplied diving equipment. Scuba has limitations of breathing gas supply, communications between diver and surface are problematic, the location of the diver may be difficult to monitor, and it is considered a higher-risk mode of diving in most circumstances. Scuba is specifically forbidden for some professional applications. Decompression is often avoided, and if necessary, is generally in-water, but may use a variety of gases.
