- I have some common sense (which seems to be lacking from some people) and can see that falling into water which is over one's head is likely to be more dangerous than falling into knee-deep water
Except that some beaches can be very deceptive with holes that move up and down the coast. Knee‐deep water can be waist deep or more within a few metres and the sea comes with wave action that's missing from most pools.
