Ah good.  There are four factors that are important for safety: dive team performance, individual diver behaviour, the environment, and the equipment.
Safety first depends on four factors,the environment, the equipment, behaviour of the individual diver and performance of the dive team
I enjoy scuba diving Oh do you? Apparently the word scuba is short for self contained underwater breathing apparatus! The first time I went under water with the mask, I felt claustrophobic and was panicky Oh I see.  Apparently there can be psychological effects due to being immersed in water and being in high ambient pressure. It is definitely a very different sensation Is it?  I know also that underwater diving has physiological influences on air breathing animals. There are some physiological adaptations made underwater, both during dives where a person holds their breath, and also dives involving breathing a suitable gas supply. After getting used to it I was fine and able to enjoy myself
