I really did not think much about not being able to work in my first 30 years of life. I took it for granted that I would have no trouble doing so until retirement age. But one day, a car clipped me when I was out riding in a bike path, and I ended up having long term pain. So much so that the only thing that helped me was a really good San Jose chiropractor a few months back. Without that help, I really do not know what would have happened. It got scary for awhile when I found myself needing to take off so much time from work.
I have always been such a hard worker.
