He is in God's hands.
and he sounds like an amazing individual...reminds me of my mom...she is 83, just had hip replacement...they let her out early cuz she's such a pistol! because of her age, people were worried about how she would fare...
this woman eats more nutritionally than anyone I know and her spirit is so much larger than her body...and after the surgery and a little down time she just had things to do...
Prayers for your uncle Bob..that it all goes well and he sails right through..hugs, grateful
