As a kid, learning to ride: turn towards the direction you're falling (dad).

Tim Krabber book: [paraphrased] When reaching a hill, change up a gear and stand up.

BF: HTFU

Race biker: this is how you change gears (demo'ing a gear shift during bike maintenance school).
Me: duh, everyone knows that.
Race biker: and this is how you shift two gears at a time.
Me: duh, I had no idea I could do that!

BF: high cadence = good for knees; float = good for knees
