What are some others please
Roll out of bed, realize you didn't set your alarm and have to be out of the house in 2 minutes -- that's ok, just get up and go, the hair-mussing properties of sleep have no power over you!
The nasty mix of rust and oil that you get from working on the underside of a car can't get stuck in hair you don't have!
I would still choose hair over no hair, but that's only because its single redeeming quality is a big one: being attractive. On most other metrics, being bald is actually pretty great.
Sure at home with an electric razor would be cheap but I tried and I can't get reach the back of my neck very well and it looks bad.
