Yes, I believe that was the particular trigger to the RSD.
I was at the party at defcon at the top of the riv. one is grossly overweight apparent fan had grabbed me around the neck, and a friendly gesture I might add, it twisted my neck and pulled me down because the pressure was too great on my back, so to protect my back I dropped down. Smashed both of my hands on a table, even that caused problems in my hands, but it was dark, and the person just fade away into the crowd, so I was not given an opportunity to approach him.
Yes it was very unfortunate, but when people around me they need to be respectful of my frailties. I mean, I'm friggin 67 years old, and I still go to these, primarily because younger folks enjoy seeing me there, and hearing some of my stories. But you don't have to wait long, I'm working on a book, and I bet you can't wait to read all about it.
No, people are fragile. They can have underlying health problems no matter what their age. Broken bones, recent surgeries etc.
If you're going to go up to someone and grab hold of them you have a responsibility to make sure you won't hurt them. It is my opinion that you should just never do this to someone you don't know.
Yup. Last Thursday I watched a co-worker grit his teeth in pain when someone came up and gave him a friendly slap on the shoulder that had just undergone rotator cuff surgery. I personally give big, hearty hugs; but only to people I massage or spar with.
