backneck

Tweet

I use the computer almost two years almost everyday, as I want to use it for my wrok. A month ago, I watched the tv paly series named woju, it is very popular these days. Two weeks later, I haved watched the paly series. However, I found I had a backneck, and I did't care for it. I knowed the reason that I sat before the computer so a long time. The backneck seemed to be getting worse, I had to go to hospital to see the doctor. So we have to notice our habbit in the life.
