“In that you never really forget how to do it, and can pick it up years and years later?”

“Yes. But that’s only part of the story. See, your body remembers riding bikes, but it also remembers doing it with a different set of muscles than you have now. So you act on your memories and assume things that are not there, and end up doing things you’d rather not do”

“Huh. I guess I never thought about it that way”

“No worries. Let’s take it easy this first time, to get up to speed”
