Should I have scoliosis surgery?

81year old male. I have left leg pain when I walk very much or far. I can walk about 1/4 mile. By then I have to start bending over to put space in my vertebae. This is especially true in the afternoon or evening. Can't tour a museum, can not shop long, my wife has to carry almost everything. BUT I get up and move well. I am around the house, up and down stairs. Sit, play cards, go visit friends, go out to meals and kids ball games all fine as long as I don't have to walk far. Neurologest says T 12 to S1 fusion and reconstruction of my scoliosis spine is really all that can be done. I my understand how big an operation this is, how my bending will be limited. Can't wipe butt, etc. So- at my age- good health otherwise. Is this surgery and recovery and limited movement worth it ? I am really torn about this. I know 2 others who had this surgery- but they were so much worse than me- constant pain. None were as old as I am.
I do have confidence in the surgery. Great medical center. Good outcomes by him. Am I bad enough for this?
