We feel backache because we have been standing or bending over, which leads to backache only when our bones and muscles can't stretch. At this time, we have to stand up and twist our waist to do stretching exercises, which can stretch our bones and muscles and relieve backache. Besides keeping a posture makes our back ache, it also has a lot to do with our usual physical exercise, because people nowadays are lazy and like to stay at home and play mobile phones and watch TV. So only exercise can make our bones and muscles develop healthily.
Bones and muscles are the frames that support our whole body. Without bones, we are just a piece of meat, without limbs and head, and bones also support our human behavior. Once the bones are damaged and can't be treated, we can only lie in bed and can't walk upright, which will bring trouble to our families and affect our normal life.
In order to make our bones and muscles develop healthily, besides daily exercise, our daily nutrition and minerals are also indispensable. For example, if we lack calcium, it will lead to osteoporosis, convulsions and skeletal dysplasia, which will affect our healthy growth. The biggest influence is our old people and children. Old people are too old to absorb enough calcium from food, so they should take calcium tablets regularly. And our children need more calcium when they grow up, which can't be satisfied in food. They should also take calcium tablets to supplement calcium.
