Karate: Is There Equipment That Can Help Me?
July 23, 2018
Much of modern karate training can be done simply by refining one's technique through careful internal reflection. The only thing required is a karate uniform or do-gi. However, there can be great benefit to using equipment in training. The use of equipment can be vital for developing a method of direct feedback regarding the execution and delivery of power into a target.

One difference between martial arts styles developed in Asia and many of the Western arts is the refinement of the legs and feet as striking weapons.

Guns, Knives, and the Hollywood Death Sentence - September 21, 2015
In order to become a successful screenwriter in Hollywood, you need to watch a lot of movies, so you can learn from the screenwriters who came before you, and so you can get a feel for what else is out there and popular today.  Unfortunately, this important part of a screenwriter's education is also how Hollywood ends up propagating and recycling incredibly stupid ideas over and over again to the point where the audience just accepts it without question.
Protecting the Brain from Trauma: A Home Experiment to Show We Can Do Better - September 7, 2015
If you put on a football helmet right now and smacked yourself in the head with your hands, you might notice you can hit yourself pretty hard before you start to feel pain.
