As a child I watched (with my father) a boxing match which lasted 12 rounds. At the end neither fighter resembled his previous pretty self, but nobody got knocked out either.
I just watched Terra Nova where the main character layed out a kidnapper in one punch. I've seen this a lot in movies. In the movies is so easy to lay someone out by landing a fairly decent blow to the head.
So I have to ask: Are movies giving an over-simplistic idea of how easy it is to knock someone out?
Or as the title asks:
Is itreallyit really as easy to knock someone out in real life as in the movies?
