An idea birthed in an Australian pub by a few friends is now one of the most envialble non-profits on the planet.

Movember takes place each November when hundreds of thousands of men and women across the globe join together to raise awareness and funds for men’s health, specifically prostate cancer, testicular cancer and men’s mental health.

Men (also known as Mo Bros) sign up online at Movember.com. Starting clean-shaven on November 1st, these men donate their face for 30 days by growing and grooming the best moustache they can muster.

Mo Bros effectively become walking, talking billboards for men’s health raising funds and awareness along the way.

Women (also known as Mo Sistas) play a key supporting role by signing up as team captains, recruiting Mo Bros, helping to raise funds, and encouraging the men in their life to take action when it comes to their health.

Mo growth is seen around the globe each November. Official campaigns are held in 21 countries across five continents, and despite it’s relatively recent entry into global philanthropy, now ranks as a Top 100 NGO on the planet.
