(CNN)As the fall chill sets in, you may see some men sporting scruffy faces. It could be laziness, it could be a fashion statement, or maybe it's a way for men to look out for each other.
Movember: Why getting hairy could save millions of men
Many men are giving their razors November off to raise awareness and funds for men's health. Men die on average five years earlier than women, according to the US Centers for Disease Control and Prevention. Prostate and testicular cancer contribute to the disparity. Also, four out of five people who kill themselves are men.
No-Shave November is one organization behind the fuzzy faces. It hopes the sudden sprouting of beards will prompt conversations at work or around town about men's health. No-Shave November is also asking men to donate the money they would have spent on shaving for the month; the funds will go to fight cancer.
If a full beard isn't your manly MO, how about a mustache?
The Movember Foundation is a top nongovernmental funder of prostate and testicular cancer research. It began in Australia (where a mustache is sometimes called a "mo") in 2006. The organization has raised $837 million across more than 20 countries.
Mark Hedstrom, the hirsute Movember spokesman, said his organization expects up to 400,000 "Mo Bros" and "Mo Sistas" to participate (women don't have to commit to the mustache part). Each participant can set up a fundraising page online, through which the organization hopes to raise $100 million globally this year.
