I gave up trying to get much of a tan long ago and use sun screen, if I'm out in the sun a lot. Not everyone has skin that can tolerate a lot of sunlight!Striking photo reveals dark side of sunshineA new striking image of a 69-year-old truck driver shows just how much damage the sun can do. This photograph, published in the New England Journal of Medicine, shows what dermatologists call dermatoheliosis — sun damage, a common sign of aging. What makes it striking is that this man, a retired truck driver, shows the damage on only one side of the face. "He was a truck driver for the majority of his life and never wore sunscreen," said Northwestern University dermatologist Jennifer Gordon, who reported the man's case. "We think the sun exposure just on this side of the face is what caused the damage." Ultraviolet A (UVA) light from the sun can easily penetrate window glass and even light clothing, Gordon told LiveScience. UVA rays cause damage deep in the skin, affecting connective tissues such as collagen and elastin. "That's where you get that aging effect: the wrinkles, the deposits of material in the skin," Gordon said. The patient in the photograph came to Gordon and her colleagues after he got tired of his grandchildren asking him what was wrong with one side of his face. So far, the man has not exhibited any signs of skin cancer, Gordon said, though he'll need to be monitored carefully in the future. The best way to prevent skin cancer as well as early aging is sunscreen, Gordon said. The American Academy of Dermatology (AAD) recommends using sunscreens that provide a sun protection factor (SPF) of at least 30, and that offer broad-spectrum protection against both UVA and UVB rays. UVB rays are the primary cause of sunburn. While UVB rays are blocked by window glass, UVA rays are not; even on a cloudy day, up to 80 percent of the sun's UV rays make it through the clouds. The AAD recommends wearing sunscreen on exposed areas of the skin daily, even during winter. "The biggest thing I've probably learned from this is that you're never safe from the sun," Gordon said.

A good topic, anna. I've been to the Carribean area 4 times, and each has been the same in one regard. People get up early to get a spot at the edge of the pool and they stay there most of the day in the blazing sun. Can't figure them out. I always find a spot in the shade. I get all the sun I need walking the beach lathered up in 45 lotion.

I am extremely fair-skinned and for many years whenever I appeared anywhere near sunlight the result was a severe case of sunburn.
I have now learned to tolerate the sun but I remain extremely careful about how much of my skin I expose and the duration of my exposure!
Lin is lucky; she is dark-skinned and the sun has little or no effect on her skin!
