There is a significant fraction of humanity that really wants magic to be real, and will perform impressive mental gymnastics of rationalization and confirmation bias in order to satisfy that desire.

If you run a martial arts academy, keep in mind that it's more productive to think in terms of business and science instead of the kind of personal politics that is a tired artifact left over from our heritage as dominance hierarchy primates,

Many budding martial artists pay only enough attention to their opponents to know where they are, and maybe if they are trying to do something right this second that you, as their adversary, don't want them to do.

My fascination, indeed my QUEST, is to hit the sweet spot in this equation as many times as possible from now until I die.

If one more "twenty-something" says to me that "age is just a number" or "you're as young as you feel" I'm going to hit them with my cane!

Isn't it ironic that exercising a lot can make you weaker?

Most of us are aware of the martial arts movie trope of the hero or villain who is supremely, indeed magically aware of his surroundings at all times.

Is it possible to become too detail-oriented? It can be if it causes you to lose sight of the bigger picture.

While the natural weapons of your body like your fists, shins, elbows, and knees can be quite formidable; without the brain to run things they are only parts to memorize for an anatomy test.
