I'm sorry to hear that, Ted, and I hope he recovers. My mom is 84 and has had a stroke but came through it relatively unscathed, so it can happen.
I am a praying man, Ted, so I will pray for your dad. I lost my mom this year. It is not easy seeing our parents age. I pray for a speedy and full recovery.
He has been taken off the respirator and can sit in a chair. He will soon be transferred to a new facility.
