I have always done that because.....As a Firefighter, I liked the ease of NO HAIR (Almost) when I have to pull my SCBA mask and Nomex hood over my head. WELLLLLL....Now that I am retired, I am gonna TRY to let my hair grow.....SOME. For the last 20-22 years, I have cut my hair weekly. TODAY has been a week. I'm gonna see how long I can take it. I am betting that I do NOT make it to Monday..... For a couple of reasons......A. My BIG TIME receeding hair line. When it DOES grow, it points to the middle, like Eddie Munster. And after a week or so, it simply feels PRICKLY!! LOLOLOL This coming from a guy who BEFORE the USAF, HAD to have his hair at least halfway over the ears and just on the collar. It was/ IS straight with ZERO style. I have a Tom Petty look.
