i enjoy deep sea diving.
[{"role": "system", "content": "Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold, or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives. Atmospheric diving suits (ADS) may be used to isolate the diver from high ambient pressure. Crewed submersibles can extend depth range, and remotely controlled or robotic machines can reduce risk to humans. The environment exposes the diver to a wide range of hazards, and though the risks are largely controlled by appropriate diving skills, training, types of equipment and breathing gases used depending on the mode, depth and purpose of diving, it remains a relatively dangerous activity.\n"}, {"role": "user", "content": "I love swimming in the ocean especially deep sea diving or underwater diving."}, {"role": "assistant", "content": "Interesting, particularly because humans are not exactly built for the environmental conditions of diving!

But not every one can do this because of the water pressure and conditions that effect the body as you have stated."}, {"role": "assistant", "content": "That's right! Most of the divers who blackout are actually experienced and strong, in fit condition."}, {"role": "user", "content": "Have you attempted and deep underwater diving?"}, {"role": "assistant", "content": "I haven't, but I have tried scuba diving. It's similar - you still use air - but it's not as deep in most cases."}]
