I have worn a beard for nearly 30 years, it is normally trimmed to about 1/2 inch. Once I did let it grow, it was out to six-seven inches and looking good. At the time I was repairing a boat, I was very hot and I was doing some fiberglassing on the underside, the sweat was flowing. Not thinking I reached up to wipe the sweat away while my hand was covered in resin, needless to say the beard was cut to about a 1/4 inch that night.
