Good news for bearded men published in the journal Radiation Protection Dosimetry found that beards block 90 to 95 percent of UV rays, reducing the risk of skin cancer. Additionally, beard hair slows the aging process of skin by retaining moisture and protecting against the wind. What’s more, shaving is usually the cause of ingrown hairs and bacterial infections that lead to acne. Bad news for bearded men: a much older study found that harmful bacteria can grab a foothold in beards. Confusing news for bearded men: A new study from the journal Evolution of Human Behavior says that men are their most attractive with a ten-day stubble rather than being clean-shaven or fully bearded. Beards are confusing. You have to have one to be a wizard in Middle Earth. You can't have one and be president in 2013.
