Getting old can really suck. Really.

So, i had a rotator cuff repair on my left shoulder ten years ago. It was doing great. Complete success. Over the summer it started to give me some trouble. But my repaired right shoulder did too. Wrote it off as arthritis. Right one straightened out. All good. The left one though...
Well, went to see an orthopedic surgeon yesterday. Xray shows bone on bone action.
He is fairly certain i need a shoulder replacement. Cat scan in two weeks.
Lets hope i grow some tissue in the next fourteen days.(like, i would appreciate some new spinal material too. But i won't get greedy)
The whole thing is a bit unnerving. I mean, shit!
