Walking back from the bar i Switzerland and this guy stepped out in front of me a little too close. He asked if I had a light (for a cigarette) and I said no, I don't smoke. He said 'Then give me your wallet'
He pushed me backwards against the wall and started to pull a knife from his pocket.
I decided that I didn't want to be there and thought punching his face would be a good exit strategy. As I went to punch him, he leant backwards to save his face and got the full force punch in the throat. Him hit the ground gasping fairly quickly.
As he hit the ground, his two mates came out of the alley already armed. I pointed at their mate and shouted 'Hospital'. During the confusion that ensured I left.
Two questions
1) Am I likely to have done any lasting harm? I know he was a toerag but I hit him out of reaction rather than thought and he didn't appear to be breathing very well when I left.
2) How long before I stop shaking with fear/adrenalin? I was tired and wanted to go to bed but am now unable to unwind.
