...Got one more procedure to go and I will be like a 20 year old - if the 20 year old was hit by a bus - but still much better than having my hip catch and my hands tingle constantly.

I believe that if you want to see true miracles you need look no further than the changes in medicine during our lifetime. Joint replacements, heart bypasses, cataract surgery and much more have been developed and improved dramatically during our lifetimes. Just a generation or two ago and we would have been crippled and blind. Modern medicine is a true miracle.
