I read an article about joint complaints and they wrote that almost all the elderly people have joint complaints. They want to find a remedy for this and they think you have to start in your early years to be sure not to get those complaints. That is why I am doing my exercises and I take some tablets to reduce the risk of getting such complaints. I want to be careful because a lot of family members have such complaints and I don't like to see what can happen with me. So I do my exercises every day, great!
