Back pain is a very common problem. Here is something that has helped me. Have your wife undergo a complex operation on her knee. Then, have her suffer the same thing on her other knee. She won't be able to drive for quite a while. She won't even be able to walk for a few weeks. You will have to take over many things that she does. The constant up and down, the driving needed, including driving her to doctors and physical therapists will keep you moving and the pain will cease from the activity.
