Tom, I heard it a lot also. I guess the bottom line is we should be protecting our skin no matter what.
Golfers, even recreational golfers, have a high tendency to get skin cancer, but they're in the sun quite a bit. Whereas morning dives are generally better because the sun is at an angle and we don't get the direct rays as when the sun is overhead, it's also best to golf in the morning or evening to avoid the more direct radiation. Of course, I golf when it's cheapest which starts around 12 noon! There is a lot of reflected sunlight on a golf course also from water and sand - I know because I'm in those areas quite often!
So can you tell I'm a retired science teacher and needed to say something?
Appreciate this thread as I am bad about reapplying sunscreen/covering up when diving and spending even more time around the water afterwards. Would like to see a biodegradable, no harmful chemical, safe for the ecosystem sunscreen spray, if there isn't one already, since I'm pretty bad about reapplying lotions (after the first app.)
