I would like to know what habits you had when you had hair but took a while before you realized that you no longer needed to them anymore.
I'll start... I started shaving my head on May 8th. Memorial Day we went to my aunt house. While I was swimming in the pool I came up out of the water and filpped my head to the right side to get the hair out of my eyes. I realized at that moment that I no longer needed to do that anymore. Once I opened my eyes to see my wife who was watching me and said "You have no hair, do you think that is neccesary?"
I personally can't say that I have done any of that which would be noticeable. Now, if we were to flip that, and i had hair, breaking my habits of being sly, i would have a hell of a mess up top from the head rub i've grown accustomed to.
Whenever I would put on my reading glasses. I would stroke my hair by my ears to bring it over the temples of the glasses.
Damn, where to do I start? Since I've gone sly I am no longer....
1. Scratching my scalp incessantly suffering from sebhoerric dermititis
2. Reaching for a baseball cap as soon as I wake up
3. Scratching my scalp....
4. Asking the Lovely Mrs. Schro to give me a haircut every week or so
5. Worrying whether or not I had enough sunscreen on the top of my head while trying to avoid getting on my horseshoe of hair
6. Scratching....
7. Looking older than I really am.
That about covers it.

I do the same thing bro....and actually just before I read this the wife made a comment about it...cause I was sitting here adjusting my glasses and i do the fingers over the ear thing to push the hair back.....just a habit...one that I dont even notice myself doing...so how do you break yourself from it?

I still have to fight the urge to even up the sideburns that I no longer have.
Hmmm...I'll have to think about that one.
Making sure I carried a comb when I went out.

I've been buzzing since 1998, but I still have a habit of putting my hand to my forehead to brush the hair back. Phantom bangs, I guess.
