Hey fellas, what's with all those mustaches? If you've noticed more than just a little upper lip hair recently on your friends and coworkers, rest assured: It's for a good cause. Movember is a worldwide fund-raising campaign that encourages men to grow mustaches in the month of November to raise money and awareness for men's health issues. Started in Australia, the month-long event came to the United States in 2008. Last year Movember raised $42 million worldwide, the core recipients of which are Livestrong and the Prostate Cancer Organization. We spoke to members from Team Boston, who just so happen to be first in the country in their fund-raising efforts.
