6:52 "Nat Hearn really makes good stuff" With now 5 years of Karate, I can totally agree to that. Probably one of the most accurate martial arts channels.
The guy was performing sanchin kata. The main goal isn't to withstand pain but for the person performing the kata to be able to focus and keep going while getting hit. Some schools use it as a way for students to get comfortable getting hit and some schools use it as a way to maintain focus. However, it shouldn't be taken to that extreme.
When fighting in your dreams impacts don't work. You have to rip and tear. you can fling around dream entities like cloth and rip them apart because your brain can't really mimic the feeling of impact in dreams, but since you don't feel any resistance, if you grab two parts and pull your brain just thinks "oh this tears really easy."
For me personally I realized this when I was dreaming as teenager and ended up ripping an attacking raptor's jaw in half.
I've seen someone use something like that liver slap in a fight. He was an old fisherman who had earned his Golden Gloves serving a a Marine in Vietnam and he used it as a counter to a hook. The guy throws a hook, he slips underneath it then tap and slap while the guy was reloading. Dude had more dirty boxing tricks than anyone else I've ever seen.
One of the most dangerous POV is that way too many people train for a duel when in real life most fights (there are statistics for this) are the few against the many.
The kangaroo guy is known as Uncle Ben, from the Texas rescue branch. He rescues animals, that kangaroo (da Baby) was raised by himself. He has also some "fights" with his evil rhea Kevin.
Obviously he loves those animals and he would never put them in danger. I think you would enjoy his vids and sense of humor
We've got Sensei Seth here watching back to back clips of the Urban Rescue Ranch and a meme with Persona 3 Reload background music... I feel personally called out in the weirdest way possible
At 9:35...a rare sight of the "grazing achilles" kick..the chi energy trails behind the physical form and does the damage a moment after...truly a legendary skill!!
