Are we all getting old or what, cuzz

seems like we are having health issues.
In 3 weeks I'm having a total rt knee replacement.
Then, if all goes well, 8 weeks later the left knee.
Been putting it off for years, pain is just too much
and the meds don't work any more since I quit drinking...lol
(Used them too much when they were new....)
But I swear, since it was decided to do the rt one
first, the left one now hurts twice as bad.....
