日記134 : Sedentary Lifestyle

When I was working, studying, or doing something, I was usually sitting on a chair. However, recently it has been said that a sedentary lifestyle may be dangerous for us, especially since it may hurt our backs. In fact, some people around me use height-adjustable tables to be able to work while standing. It sounds really tiring to me, and I don't like their designs, but these days I sometimes feel bad about my back. My posture, both standing and sitting, isn't good, so I should pay more attention to my back health.
