The Naked Man Problem and the Secret to Never Forgetting Numbers

Crap. Where did I put my stuff?

Every time I go to the gym, it’s the same thing - a sea of identical lockers. And I have no idea which is mine.

I can’t solve this by picking a favorite, because there’s always a potential naked man standing next to the one I want. This isn’t a big locker room. And I like my space free of other naked people.

(Maybe it’s because of that time in college when I was just trying to find a bathroom in a campus building and accidentally walked into the locker room my chemistry professor used after racquetball. Naked chemistry professor. That image is burned into my brain forever.)

So yeah, there are plenty of times I come back to that locker room and have no idea which locker is mine. I know I’m not the only one. You can see the panic of guys opening locker after locker, trying to find their stuff.

But here’s my secret. I actually do know how to remember mine.

Swans like boating on a sailboat while smoking pipes.

There it is. My locker: 246.

Swan = 2 Sailboat = 4

Pipe = 6

It’s just a story.

You’ve probably heard about a “memory palace.” It’s that technique where you remember things by placing them in imaginary rooms in your mind. You think, “That sounds cool,” and then never try it because it sounds like work.

It’s not, really. But here’s something even easier than a memory palace.

The One-Minute Memory Hack #

Just turn numbers into a story.

Use images or symbols that are fun for you - something weird, vivid, even a little ridiculous. Your brain loves to remember weird.

Here’s my personal number dictionary for inspiration:

Number Symbol
0 Donut
1 Candle
2 Swan
3 Heart
4 Sailboat
5 Hook
6 Pipe
7 Axe
8 Snowman
9 Hammer

And yeah, I know - a 6 and a 9 kind of look the same depending on whether you’re standing on your head. So come up with your own unique pair if that bugs you.

The trick is: you’re not forced to use anyones. Use your own. The only rule is to keep them consistent. Once your brain associates “2” with “swan,” it’ll never forget it.

For example, there’s a lock in our house no one can ever remember. I don’t know the code either. Except… I can axe (7) the head off a swan (2) and hang its beating heart (3) on a hook (5) — and boom, it opens.

Yes, it’s gross.
But I’m never forgetting it.

Happy Halloween.

    All I got from this is people need to get over being naked / seen naked.

    In Japan it's common to get naked with strangers people of the same sex at a hot spring. IIUC in Finland it's common to get naked with strangers of all sexes at a sauna.

    In the past, in the USA it was common to take communal same-sex showers in PE class in junior high school and high school.

    But sometime in the past 40 years, that seems to have changed in the USA. I've met lots of 20 somethings and 30 somethings that can't handle a sauna or hot spring because they claim they've never been naked with anyone else. WTF!

      Finnish sauna enthusiast here: going to same sex sauna naked is absolutely common (although you'll also find people who avoid it), but mixed sauna is less commonly done.

      Amongst technical university students it used to be effectively universal that sauna was all mixed and naked. At some point it became common that some people, females especially, would wear swimsuits into sauna. It has also become common that before mixed sauna there is scheduled separated sauna turns for those who want to go but don't want to enter mixed. (Scheduled so no one has to raise their hand up and publicly say "I'd prefer to go without mixed bathing.")

      In private life, a mixed naked sauna between eg. close friend families is something I consider pretty normal and do frequently enough without really blinking an eye. But that's because it's between two sauna-crazy families. It's all pretty dependent on the person or people.

      I find it comical that modern beachwear leaves almost nothing to the imagination and nudity is still taboo in some cultures.

    How sad. I wonder what the deep problem is. Religious, cultural, something more serious.

    Imagine not being able to go to a sauna, or shower in public, because of a fear of people.

      How does a preference become fear?

      I am not afraid of other naked people, but I have had it once too many that certain people in e.g. a hotel sauna (for context, this was in some boutique hotel in Southern Germany) do not respect personal space, and the whole sauna naked thing becomes performative and annoying.

      Once the nut-sack of a 160kg weighing Bavarian man makes a near hit with your chin as the man tries to climb over you to the bench at the back... anyway.

      I found this with a significant amount of the naked sauna goers t.b.h. the claim of additional health benefits has been thrown at me, which is such obvious bullshit, it merely emphasizes the performativeness of it all.

    Talking about memorising numbers, one should definitely mention this well-known system which maps consonants to digits: https://en.wikipedia.org/wiki/Mnemonic_major_system

    With a system derived from that you can quite easily learn to memorise a shuffled pack of playing cards, by which I mean: someone shuffles the pack of 52 cards and deals them out in front of you, one card every couple of seconds. An hour later you are able to recite the sequence of cards forwards or backwards. (But you can't do random access! What you've done is associate each card with its neighbours, so you can step through them forwards or backwards, without necessarily knowing which direction is which.)
