Thinking on that theme. My 89 year old Mother in Law is going to find out today that she will have to be hooked up to oxygen 24/7. It will be interesting to see what she does with that information.
My daughter-in-law is hooked up to oxygen 24/7. It doesn't stop her from being a school teacher, nor from traveling to visit us.
My first wife (God rest her soul) was hooked up to ambulatory dialysis 24/7. She lived a fairly good life that way for the five years until her death.
I hope your MIL fares as well.
Hopefully she’s a non-smoker.
Prayers for your mother in law.
