[Faust]

Quote:

What I do is imagine that I'm hanging from a string that's attached to the front/top of my head.

This.
I worked on a project last year where a karate teacher talked about how to use martial arts stances in every day life: to avoid slipping on wet surfaces, or move quickly without hurting yourself. Whenever he discussed posture he would always say that exact phrase: imagine you're hanging from a string that's attached to the top of your head.
