That’s good news.
It may sound corny, but prayer is very important.
My brother in law (31) had a stroke and several bleeders in brain about three weeks ago. He was in good shape, soccer/basketball player no health issues then BAM!
His sister lives in CA, she set up some kind of prayer blog online. It was amazing to read. As he rehabs and learns to walk and talk again, he reads that thing several times a day.
He should have died, everyone prayed for him. He ended up at Boston General with a bunch of brain surgeons and long story short he’ll be back to work in two months!!!
Prayer and following Dr’s orders, your dad is in my prayers.
