I used to wonder why we were doing what I thought were "Useless techniques"?
Until one of us had a weapon, attacking/counterattcking with bokken or jo, a lot of things seem useless ... kind of like ... why do them football guys want to push a coach on that sled thingy?
Where would you ever use that in real life?
Pushing a 300-400 pound boxed item like an outboard motor onto a hand truck maybe? I've done that for over twenty five years, not everyday but when I had to, and moved up to 600pound boxes with nudges to get them out of corners and into position to unpackage. If I had only known to use sounds and some Aikido technique, it would have been that much easier.
You never know when some silly technique actually translates into real life?
