This gentleman decided to grow out his beard while hiking the Appalachian Trail. That is an entirely appropriate and badass reason to grow a beard. It's much better than just growing it every day for a year and having it reduce your attractiveness. This is a beard with a purpose, unlike hipster beards decorated with holiday ornaments. It is a beard reflective of one man's journey, not a bunch of beards that get people mistaken for terrorists.
It takes approximately six months to hike the entire trail, so we'll assume this hike is something that was on this guy's list for after he retired. Or maybe he just really kicks ass at being unemployed. And while hiking the Appalachian Trail gives you an excuse to take fewer showers, hopefully his beard didn't collect too much of the same bacteria found in poop.
