Please note: this is a correction to my post from last night....
Ok, WS poster gngrsnap gave me a brainstorm and I decided to explore JHs driving route a little more. When they mentioned that JH had to pass a hospital, I decided to look at hospitals on his route. Wow!
Below are driving distances of hospitals from his office (Home Depot Inc, 2455 Paces Ferry Road Southeast #20):
2 minutes away (and on route): Kaiser Permanente Cumberland Medical Center, 2525 Cumberland Parkway Southeast (thanks to gngrsnap!)
5 minutes away (just on the other side of his building): Emory-Adventist Hospital, 3949 S Cobb Dr
or
6 minutes away: Uncle Maddio's Pizza Joint, 2955 Cobb Parkway SE
So. What this means to me is, to get to Uncle Maddios, he bypassed 2 hospitals. Even if I forgot my child at 3 opportunities through the day, when I was in his vicinity (+ never spoke to my spouse during the day and have the child come up in conversation, and think back to the morning? Spouse wouldnt ask, esp. if the child had been sick two days, How was he when you dropped him off?), and I found him in the car and knew instantly hed been there 7 hours+, I would drive straight to the hospital that was 2 minutes away, not some Pizza Joint! Even if I was past the hospital, Id go back instead of to a place with no care, where we had to wait for EMS.
I think it is a good possibility that emergency services thought of this when they arrived and heard his story.
