After a difficult transport that caused a good amount of discomfort, Bat will undergo many tests today at Mayo. They've been upfront with him and asked him if he has his things in order, if he's made arrangements, about a DNR. It's SOP for people at his stage of life, but it's also a legitimate indication of the stark moment he's at.
The test will help Mayo determine if there's anything that can be done, and what can be done.
Dad had a restless night filled with prayer. He's asked God for more time. God will answer this prayer soon.
