I should exercise steadily. I heard of the news that the muscle will be decreased by 1% every year after the 40-year-old. The news said, it's hard to recover muscles after losing it, therefore we have to do muscular exercise to prevent it. Actually I'm afraid to get looking like those old man's thinner bodies whenever I see them on the street, it's not far for me. I hate to exercise but like to take for a walk for 1-2 hours a day. But it's said only walking is not enough. Forties have to run till out of breath or do muscular exercise to prevent losing muscles. So I took out a jump rope from the dawer which I had bought 10 years ago, but new one, unused, not even once. As I told her my plan doing jump rope, my friend said, urine will come out while doing jump rope. It was terrible though, I thought I would be okay cause they had given to babies, not me. I was out of breathe after jumping rope 100 times. Fortunately urine didn't come out. hehe ; I hope I do exercise hard...not even if exercise hard, steadily!
