US Hawks Hang Gliding Association

I just had a thought this morning. Yes, you can thank me for the warning.
What if arthritis has a root cause of poor or restricted blood circulation.
Cells that are improperly nourished, may be weak, or dying.

Does the immune system try to remove these unhealthy cells and hasten our immobility?
Are drugs like Enbrel, that slow our immune system’s work, effect only a symptomatic treatment when all along restoring adequate blood flow is the cure?

Exercise seems to help. Is it because exercise promotes better blood circulation?

Does repetitive high impact motion cause arthritis because the damage done is simply staying ahead the body’s ability to repair a joint depending on its blood circulation rate?
Just some thoughts for the people in this field of endeavor to ponder.

I think it's a great theory Bill!!!

I'm not an expert on arthritis yet (crossing my fingers), but it makes a lot of sense to me.

Maybe you should apply for a federal grant to study it. You can compare the arthritis rates of people who are sedentary to people who do something active like ... oh I don't know ... maybe hang gliding?   

One thing is for sure. They do say that keeping your mind active will keep it functioning. I'm not seeing any signs of arthritis in your helmet holder!!
