Forgot the info portion...
I am a sly guy in my twenties. Although by choice. I have had numerous health issues in the past 2 years including kidney cancer that have caused extended stays in the hospital and I have found I feel just a lot better when I don't have to worry about any hair during those times, especially considering those stays often start with a 3-4 day period in which I cannot get out of bed to shower (I know, gross, right?).
The very first time I shaved 3 years ago was when I lost a bet with a church youth group and while I have grown my hair out since then, I always find myself wishing for the great feel of a freshly shaved head.
