Worse sunburn I ever had was back in college. Went out for a spring break trip to Copper Mountain and Keystone - I wanted a ski tan so stupid me, I used no sunblock at all. The sunburn was so bad I had blisters on my lips and developed a fever.
I am 100 percent Danish with a really fair complexion, blue eyes and reddish/blonde hair. Today I am paying for the stupidity of my youth. I have had malignant melonoma but they caught it early enough with surgery.
Actually I am on the "cancer survivor" mailing list - I never have thought of myself in those terms, but I guess it could have been bad if not for the early detection.
When skiing I really cover up and with any exposed skin (basically only my nose) I use a high SPF sun block. In the summer I only do yard work in the evening when the sun is low. Plus I have to go in for screenings twice a year. Believe me, they check
everywhere. Even areas that never see the light of day! There is no modesty during a skin cancer check.
