Take a look at this photograph published in an article in the New England Journal of Medicine. (You can see a larger photo by clicking on the link.) It show the asymmetric skin damage on the face of a 69-year old truck driver due to the many hours driving with just the left side of his face exposed to sunlight.
Those of us who grew up in the tropics avoided staying out in the sun if we possibly could. We sought the shade and I still find it strange when at the first sign of warm weather in the spring, people here in the US rush to lie out in the sun in skimpy clothing.
Of course, us brown-skinned people don’t feel the need to get a tan and in fact in many tropical countries having a pale skin is a desirable sign of wealth and privilege and is flaunted, since it shows that one lives a life of luxury that does not require outdoor labor.
Noel Coward’s song “Mad Dogs and Englishmen” made fun of the crazy behavior of the British colonials in the tropics, ignoring the avoidance practices of the locals to show their disdain for the dangers of sun and heat. (You can read the lyrics here.)
