I must do more exercises I haven't done exercises for several years. In my impression, I just did exercises when I was at school such as taking the PE lesson, running in the morning, playing football in the playground, etc. For couple of years' work, I always stay at desk with computer and have few exercises. So it isn't healthy enough for me to keep the status. It becomes better these days. And finally it shows the sunshine. With the warmer and warmer weather, I decided to ride to my office now. So, I got an old bicycle from my friend and wiped it clean. From this Monday to Wednesday, I continued to ride between my office and home. It costs me about 45 minutes in one way, I feel my leg ache now, becuse I've no such amouts of exercises recently. I am doubt that why the others ride so fast by passing me. And they seem not pedal much frequently than me. Maybe my bike is too old to circle. And I need to give some oils on it, so that it can work better I think. Anyway, it's a new way to go work and I needn't to push or pull myself on my way home or work. And I don't like the crowed people in the metro with the bad air beneath the ground.
