There is significant danger in waiting until you get very sick- you are not a good candidate for surgery then, especially if there is an infection too. I had mine out at 47- early laparoscopic days. My daughter had hers out at 19. You have to sign consent for open surgery in case it becomes necessary due to complications.
I am also 70+ and have realized my body is not as tough as it used to be even if my brain says I’m around 35!
