Yeah, I may not be understanding G forces correctly, which may be part of my problem.

And worrying really seems to be my problem. But just a few hours ago I tapped my head when entering the car (I'm having rotten lock with this), and even though I was super anxious, I was able to convince myself that I didn't have any immediate symptoms. And now I'm feeling fine. So i think I may be heading in the right direction worry wise!

John,

Good job.

You can use this incident for future reference to defeat worry...the facts of today's bump proving to be nothing will help you to identify anxiety the next time and put it to rest.

Anxiety I concluded from my injury is a very clever and persistent liar. Truth can defeat it but we must be persistent about the truth also.
