"An obvious initial complaint in applying these findings to humans is that people typically do not eat sunscreen." Yet the story begins with anecdotes about smearing it all over three year old kids. The author apparently does not have children. One convenient probably fairly low risk solution for sun exposure is clothing. Cuts back a lot on mosquito bites and minor cuts -n- scrapes. I've been told over and over that my baggy pants and baggy long sleeve shirts will give me heat exhaustion on the hiking trail, exclusively by people who refuse to try it, and are instead smeared with a 1/4 inch layer of sunscreen and bug spray goo which makes them look more miserable than I actually feel. This probably won't help on the beach but for the other 99.9999% of life time it does help. It is true that they can survive 90 degree weather when I quit at 85 degrees, but when its 85 degrees out, going for a couple mile hike in direct sunlight is not my first choice of leisure activity anyway, so it doesn't really matter. Personally UV caused cataracts leading to blindness or a financial death penalty scare me more than a mere easily detectable and removable skin tumor, so I reach for the UV proof glasses before I even think about sunscreen anyway.
