Is there a standard definition for the darkness of a "base tan"? Darker skin can make a big difference in how resistant one is to a sunburn. A dark African has a MED (miminal erythemal dose, the quantity of sunlight to produce a burn) about ten times that of a light Northern European. Even just brown skin has a MED five times that of the lightest skin.

On a somewhat related note:
My skin has been so dark by the end of summer that during a road trip in university one of the girls asked me why I left my underwear on when I mooned the passing cars on the highway during a pit stop. She thought my white behind was a pair of tighty-whiteys. Hey, I was 20!

Dilbert does not understand SPF. Take the SPF number (4) and calculate its reciprocal (25%). That is the amount of UV radiation that the lotion allows through. An SPF of 4 BLOCKS 75% OF THE UV!!!! That's pretty good, I would think. Please note that the difference between not using ANY lotion and SPF 2 (50% - 0 = 50%) is greater than the difference between SPF 50 and SPF 2 (98% - 50% = 48%)!

It was Dilbert who should have taken the flying leap, although I agree the female deserved some sort of attitude adjustment.
