I was recently thinking about how harrison mentioned that you should be prerpaired to loose some hair if you are regulaly using a 21" CRT monitor.
This made me wonder if the 21" monitor could be the reason why the hair on the top of my head (which a few months ago, was quite long) was very easy to pull out. It didn't fall out but it did pull out easily, resulting in a large amount of long hair being scattered around my room.
I shaved it quite short a month of so ago and have had several commonets on how I am going bald. This is quite obvious now, although I noticed it myself when my hair was still long.
It is only the hair at the top of my head that pulled out easily though. The hair at the back, front and sides was still quite difficult to pull out.
