Excellent post #45.
You have a very lucky son.
Thanks, you're very kind. I worked out my own concussion protocol, and it's been used once. He got his bell rung a couple of years back. I went down to him and asked three questions:
What happened on June 6, 1944?
What happened on March 6, 1836?
What happened on November 22, 1963? He didn't answer it reflexively like the first two, so I gave him a hint: I was in 4th grade when it happened. lol
He was fine, but his teammates looked at him in awe: how did he know those dates? lol
