Grew a beard in my 20s, looked like Grizzly Adams. I found it annoying and shaved it off after a few months.
At my age(63) I am afraid to grow one now. Some bozo hunter might mistake my snow white beard for the south end of a north bound deer and send a bullet my way.
This may sound far fetched reason to not grow a beard but you never know.
A former manager at the power plant I worked at was hunting on public land outside Chattanooga, dropped his pants to answer natures call, some idiot saw the white of his underwear, fired a shot at what he thought was a deer and killed the man.
