Redhead, blue eyed devil here.
I avoid the sun like the plague. Probably for the best, I did it because I despise the sensation of being sunburnt, rather than thinking long-term about cancer.
Although, I've collected some major second-degree burns over the years anyway. Last one was in '96 when I was just dating Mrs. Dual and sat in the bleachers with her family for her college graduation commencement. It was only early May, and quite cold, but the whole right side of my face cooked and all the blisters just connected up into one big one.
I figure that the combination of mega-burns, and studiously avoiding the sun puts me into the 50/50 risk category. Hopefully its constant long-term exposure that does it rather than infrequent bad burns.
Thanks for sharing.
I've found with the new spray sunscreens that it's much easier to apply, and gives me less excuse to not cover up.
