CE,

I jumped out of a truck once at work to do something and briskly walked into one of my work plane wings just above my forehead. I ended up falling backwards onto my head on the concrete pad I was on.

This was before I knew about concussions. I got up wondered what just happened and went about my business and spent my time worried about how dumb employees thought I might actually be.

If that happened today I would probably spend a few days combating worry about a concussion sending me over the deep end.

I would think you are ok and should work on reminding yourself of just that.

Bud
