If you’ve never been a fan of using sunblock, here’s a startlingphotograph that might change your feelings toward it. Shot by doctors Jennifer Gordon and Joaquin Brieva of Northwestern University and published by the New England Journal of Medicine, the photo shows a 69-year-old truck driver who exhibits a strong case of photoaging. In the 28 years he spent driving trucks, the man’s face received far more sunlight on the left side with the sun streaming in through the driver’s side window.
