Have you noticed more mustaches sprouting up [1] this month? In honor of Movember [2], men are ditching their razors and growing mustaches during November to bring awareness to men's health, particularly prostate cancer, testicular cancer, and mental health. They shave clean on Nov. 1 then grow and groom their new mo' (slang for mustache) for the entire month, asking friends and family to donate for their efforts. Like walking billboards, when people ask about their 'stache, it's an opportunity to spark conversation and raise funds for these often-ignored issues in men's health.

To get you in the spirit, these two guys made an amazing video about it appropriately called "Let It Grow." Hooray for another "Let It Go" parody [3]!

It's not too late to get started, even if you're a woman: become a Mo Sista and sign up here [4] to support the men in your lives. If you feel bad that you can't grow a mustache, why not grow out your leg hair? Or just ogle these hot guys with beards and cuddly animals [5].
