I have a very full head of hair at nearly 57, buy many moons ago when I was coaching my sons’ football teams, I shaved my head. I just didn’t have time to fuck with my hair and really had no inclination to do so given the then horrific state of my marriage. I loved it. I looked mean. I ran into my current wife at the airport and she didn’t even recognize me! Eventually, vanity took hold and I grew my hair back out. But man, if I ever start to lose my hair, bam, it’s getting shaved again because I really loved it that way.
