What body part has ultimately failed you?

I always thought my lower back would do in my running but i learned how to prevent my back from going out. Now as I pass 50 a front runner has emerged, my knee has arthritus and I cannot run 4 miles without pain. 2 operations have not helped.
So if you could pick one body part that you wish was healthy what would it be and why?
