Between contemporary politicians, musicians, actors, and athletes, I should get most (if not all) the way there. Sprinkle in a few historical figures and I'm home free. In case of emergency, I can always dip into my stash of streamers which alone could easily get me halfway to the finish line because I have permanent brain poisoning.

If you asked me this 10 years ago I could probably do it with K-Pop idols alone, but nowadays I don't think I could pull it off, at least not without some visual aids or something to jog my memory. I think they'd still get me to about the halfway mark, though.

I think I might actually try this after I've gotten some sleep and post my results--seems like fun to see how fast you can do it! I'll first try it without the more niche categories (how many of you are actually gonna know I'm not naming some random person if I say Lee Soon-kyu?) and see how far I get. I think the strategy is probably to prime your memory with groups rather than going one-by-one (e.g. for actors, think in terms of franchises or TV series; for athletes, think of specific sports or teams; for musicians think of genres, eras, or groups; for politicians, go by administrations, governing bodies, states, etc.)

One rule clarification: how strict are we on needing first and last names? For actors, politicians, and athletes it seems non-negotiable, but a lot of singers go by mononyms or stage names. Some of them seem like fair game, but others seem like cheating. Like, do you really know the Spice Girls if you can give their "Spice names" but not their real names? I think I can get all or most if the former but only one if the latter (the most famous one), and the latter seems fairer to me--I doubt I'd even recognize the others' names if I saw them, or even recognize them if I saw their photos outside of a Spice Girls context.

edit: I did it! Fun exercise--would be nice to try it again further down the line (not having been primed by reading some of the other lists) with additional restrictions.
