You should see the other guy. Got rear ended tonight

No. You're not ok. Your neck hurts. lol

Seriously, you can feel injured/sore/have problems later. Please get checked out by a professional and physically take it easy for at least a week. I have heard of guys afterwards that reached down for the paper, fell, and could not get back up, or neck injuries, etc. If you are like many of us, you are not 18 anymore. :)
