Sunburn

It seems to me that there is a simple choice. We can choose more than one option.

  • Get sunburn and a risk of skin cancer. (As I understand it, skin cancer is not causally dependent on sunburn, but they both depend on UV - sunburn via dehydration of skin cells near the surface and UV via mutation of the DNA in skin cells. Of course, it's possible that slightly dehydrated cells are more susceptible to mutation because their protective thingys aren't working as well - I'm not a biologist.)
  • Rub in some concoction of all sorts of chemicals which almost certainly haven't been tested for long term effects of repeated exposure to human skin.
  • Wear long sleeves and a decent hat.

Now, to me, the choice looks simple. But that might explain why I now have a sunburnt right ankle.
