Some initial training in the uk with the military. A little in Brazil (that was more for fun) and a week in India. The last was where I got brained with the bat. My fault. It was the last day and I tripped while practicing defence.
I find it somewhat hilarious that you had a clear demonstration that accidents can happen in fights, yet you still advocate escalating to violence before verifying if the violence can be avoided altogether.
I refresh every couple of months.
