The simply things in life like exercise are so amazing for us. At work I have back problems, yet they completely go away as long as I keep my core in check. I did this by simply buying a pull up bar for easy upper body workouts and almost like magic, the pain is gone. As an aside, physical activity (mild lifting weights, and pull-ups) also seems to stay off repetitive elbow pain I was having from computers too.
We're simply machines being used wrong and seeking incorrect fixes. Medicine is obviously needed in many cases - running won't fix everything.. but I wish doctors would be harder on people. We know what helps, we know what fixes things. Doctors seem almost to be enablers, more than anything. Almost to a harmful degree..
