"Not survival tips for the wilderness, but survival in urban surroundings - basically any tips on how to handle a street fight - any of the vigilante rubbish you see on TV.

I have a close friend who was a UK Royal Marine - he was, in effect, a violence professional for a decade or so. He told me that the vast majority of his training regards hand to hand combat involved the following:

- Assume your opponent is armed even if you can’t see a weapon

- Run away as fast as you can

- If they are close enough to touch you, push them as hard as you can - hopefully they’ll fall over - then run as fast as you can in the opposite direction.

That was it - just get away from them as fast as you can. Don’t try and engage in a fight with someone you don’t know because you’ll probably get k****d."
