Handwashing.
The physical technique that I think is the single most important thing for people to learn is, in the words of Geoff Thompson, 'the Fence'.

How does the "fence" differ from Tony Blauer's "spear"?
Ummm, yeah, that's the Chum Kiu from Wing Chun Kuen.
Is this more of that "modern combatives" stuff that they steal from Chinese martial arts and then sell it as "Th3 d34dly"??? Instead of Seeking the Bridge they call it "The Fence" now? Well, OK.
What did they call the Chum Kiu in RBSD, the "cowcatcher" or something?
Having your hands up in a fight is a "technique"?
Everything old is new again!
Does that mean that everything evolves from Wing Chun?
Does that mean that anyone unwilling to invest the amount of time that you do is unworthy of learning good technique?
The idea of having your hands up, in a nonthreatening, nonstylized posture whenever interacting with people of unknown intent is an important concept that a lot of people do not appreciate.
It's not simply 'keeping your hands up in a fight'.
eating?
The wu sao is somehow not appreciated? Something present in every form of boxing is not appreciated? Got me there. Don't understand that at all.
