Let's see, I got sun poisoning driving to Florida in my parents Volvo with no a/c and crank windows in about 1988.
As for sunburn, I was in Jamaica in April and decided to go snorkeling from about 10 am to 3 pm without any sunscreen. I felt fine until I came out of the water and flipped my hair onto my back after floating in the water all day. Then the chills began. I had to shampoo my hair in front of my face for the rest of the vacation. It was so bad that it took about a week to even blister, it was so deep.
Owch. Still, I'd take it any day over hypothermia
The morning star always gets wonderful bright the minute before it has to go --doesn't it?
