my wife and i like to go scuba diving.
[{"role": "system", "content": "Scuba diving is a form of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver through a regulator. They may include additional cylinders for decompression gas or emergency breathing gas. Closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases. The volume of gas used is reduced compared to that of open circuit, so a smaller cylinder or cylinders may be used for an equivalent dive duration. Rebreathers extend the time spent underwater compared to open circuit for the same gas consumption, they produce fewer bubbles and less noise than scuba which makes them attractive to covert military divers to avoid detection, scientific divers to avoid disturbing marine animals, and media divers to avoid bubble interference.\n"}, {"role": "user", "content": "I've been thinking about my vacation this summer.

You don't need certification and it's less time-consuming."}, {"role": "user", "content": "Oh wow, thanks for the advice. I wonder if the resort I was looking at will offer introductory sessions. "}, {"role": "assistant", "content": "They probably do! Introductory diving is probably better, because you'll have a diving instructor guide you around. "}, {"role": "user", "content": "Oh that makes sense. I'm interested in all of the creatures under the sea. "}, {"role": "assistant", "content": "Scuba diving is definitely a great way to experience that! It's best to avoid touching anything though. Try not to disturbe the marine animals."}, {"role": "user", "content": "Yeah, I'm sure even just exposing the marine life to human is disturbance enough. "}, {"role": "assistant", "content": "Definitely. It can be. Not to mention, humans aren't physiologically well adapted to underwater diving. "}]
