I was writing a scene where a guy was choking another guy to death. You can go online and type 'chokeholds' and watch scenes where martial artists choke each other out. You can hear what noises they make when they go unconscious see how their bodies flop and everything. YouTube is amazing for the more detailed stuff.
I travel Europe every couple of weeks. I just came back from London Holland and Denmark. Every nation on this planet has its issues with race and I am not sure if everyone has figured out how to deal with it.
