Trust me Chris I saw it in a documentary. There are some extraordinarily brave & good people & their are some who are outright evil. Remember the fireman at Kings Cross who ran down to save another person & was burnt to death? He probably knew the odds were 100 to1 against, but he went anyway. That was his job. The Chernobyl workers who went into deadly radiation zones

I will endeavour to find the information

I am not at my best at the moment
