There are two types of people who are prone to it: one is people who work long hours bending over, such as porters. The other group is people who work in a sitting position for a long time and lack physical exercise. Some people wonder: I sit all day, but I do not use my back ah, how did the strain? For example, you use your arms to end a very light cup, a few minutes you do not feel, if the end of the morning, your arms must be sore.
