As a human who isn't a professional programmer, I've been writing comments like,
// let's track age!!
// this is harder than you'd think as I with totally impressive
// foresight didn't add age to the raw data.
//
// More honestly, I didn't want to add age to the astro data as that's
// a calculation that can change depending on how you slice it.
//
// Hence we need to figure out their age first.
