Sorry, I've been out of touch. I just returned from Washington, DC where I was visiting my mother, who has been ill. She was hospitalized the Monday after Easter with pneumonia. During the 12 days she spent in the hospital, they didn't have her up and walking at all (to regain her strength).
She was released a week ago Saturday (the day I arrived). By her third day home, it was apparent that she really wasn't ready to be released straight to home. She's back in the hospital now and will be going to a short-term in-patient rehab program soon.
It's difficult because she's always been very independent (works full time, lives alone). But there's no reason to think that she won't be able to return to her former level of activity after she rebuilds her strength and stamina.
Still, say a little prayer for a speedy recovery.
