Spaced repetition systems have gotten better

My "Daily Life" deck is pretty small. But I fill it with things whenever I try to recall something and am embarrassed to not know it. Now I know them!

- Population of Tokyo / Tokyo metro area / Japan (where I live)

- Japan emergency numbers (like 911/411 in the US)

- kg <-> lb and km <-> mi conversion ratios

- My Japanese phone number (and my wife's)

- Number of neurons / synapses in a typical human brain

- Number of parameters in SOTA language models

- How many people work in my office

- Last 4 digits of a couple important credit cards, so I can identify them when UIs present me a choice of pre-saved CCs.
