Knowledge: To play golf safely, the location must be an open grass field to ensure no one gets hurt. Also, scuba diving can be done anywhere as long as proper equipment is used.

Conversation:
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.
Oh I see. So where can one scuba dive safely?

Response: Ah yeah. As long as proper equipment is used, scuba diving can be done anywhere.
