Be sure that you bend you knees when you are doing your garden and lawn work. You do not want to hurt your back. And it can be a great strain on the knees too. I find that if I do not bend properly that I am in pain for quite sometime. And this can be avoided too. Do not pick up things that are too heavy. Know your limits because you could do serious harm. And get help when you need it. You do not have to do everything yourself…even though that is what I think all the time!
