Just because the mass of the planet pulls us toward it, doesn't mean that everything is "straight down".
"And a horse can't give milk and a cow can't whinny and down is up and sideways is straight ahead"... but what exactly does that have to do with the discussion? I mean if you don't have anything to add that might help people who want to learn to do that why post on the thread? I don't believe anyone said everything is straight down.
Some of us here are interested in understanding the mechanics of breakfall and what the good and bad points might be. Others seem to be against teaching them at all. Well that's ok too. But if you are can you at least give some useful discussion as to why and hey how about you make us a video on how to deal with something like say a fast koshi without taking one?
