Status Quo vs. The Party Of Change

"...two important aspects of inorganic chemistry (in fact, of chemistry in general) are structure and reactivity.  Someone has said that all of physical science consists of this duality. In physics we could speak of statics and dynamics, and by analogy in everyday life, the status quo and change."

~James E. Huheey Inorganic Chemistry: Principles of Structure and Reactivity 2nd Ed

Yoga practice fits nicely into that dichotomy when juxtaposed with aerobic exercise. Yoga is rather static and structural, consisting of lots of stretched poses. Cross-country skiing--which I've done a lot of lately -- is very dynamic. I'm now doing both on a daily basis. 

Another analogy is political: Conservatism is inherently status quo; the other wing is by nature about change and dynamics. Best to take a little of both in measured doses.
