One of the benefits of early male pattern baldness. :)
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.
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.
