Interesting how different people's minds are. I find the exact opposite problem, I go with old faithful over new. It's for this reason that when I put my clothes away I simply take the stack of clothes in my dresser out, put all the fresh stuff on the bottom, then put the clothes that were in the drawer stuff on top. I always grab the top sweater, t-shirt socks etc and I don't think about it at all.

FILO is not the standard method of maintaining one's stock of clothes? How else does a person mange wear leveling?

Lol, since we're going down this road... my clothing ends up getting stored more as a cache with an LRU policy. Every 6 months or so the items at the bottom of the drawer get assessed for eviction (donation). My favourite items are always on top, less used items are easy to find, and the unused items are easy to identify.

I was intrigued to see a lady at the crosswalk the other day wearing earbuds with thick tubing instead of wires. Googling it, I discovered they were "EMF free headphones". Apparently enough people think electromagnetic radiation in the ears is a problem that there are now dozens of these headphones on the market that put the driver half way along the cord, with tubes proceeding to the earpiece.

To be fair, EMF is 1/r^2 so the transducers (speakers) are indeed far from the ear. Not that they need to be, but...

They're also more durable; i.e. resistant to running over the tube portion with a chair.

This guy also has a post about the hierarchy of socks and underwear which resonated with me. https://tomlingham.com/articles/an-unfortunate-hierarchy-of-...

There's a sci-fi book I read a while back that had as a plot point an alien species that had algorithmically optimized its decision-making processes so much that it was no longer recognizably conscious. I think about that now and again when I get a little too invested in some system or practice.

Was it good? Do you have the title?

You shouldn't. If you successfully manage wear leveling all you've done is make sure you have to replace your whole stock at the same time, as well as depriving yourself of regular reminders of what new-ish clothes should look and feel like, leading you to keep wearing worn-out clothes.

With socks, wear levelling is actually really useful. I tend to buy a whole rotation of identical black socks, and then I don't need to pair them up individually. Also, buying 15 pairs of socks in one go isn't going to break the bank.

tldr it's a pneumatic tube like a stethoscope. these used to be used within aircraft as well for inflight entertainment.

I've been on an airplane that used these! I think it even had a channel selector near the plug if I remember correctly (it's been a while).

I remember being able to select the pilot coms. I was nervous on my first flight as a kid, and it was very calming to hear the preflight checklist and ATC communication in the classic pilot cadence. This was pre 9-11.

I did wonder on my last flight if I could use SDR & android to listen in.

>The only headphone tech that I was aware of or that I'd ever really considered I guess I'm old now because this style of headphone was present on every model of passenger aircraft in the sky when I was a young adult.

I've never heard this before! When I started flying it was just the 2 mono jacks that you still see on planes that haven't been updated (always wondered why it wasn't just a stereo jack) Pretty surprising to hear there's air/sound tubes rigged on to every seat on a plane. Seems like the sound tubes ended in the 70's: https://apex.aero/articles/sound-tube-surprising-history-air...

apparently the speaker was in the armrest.

They also use a similar mechanism for the "get me out of here ASAP" panic button [0] that staff place in your hand and tell you to squeeze if required, all it does is detect a change in air pressure on the other end of the tubing. [0] https://www.mriequip.com/store/pc/MRI-Non-Magnetic-Magnalarm...

My house came with a button like that for the garbage disposal. Previous owner didn't like the idea of using an electrical switch with wet hands.

But what's the use in that "useful"? When I pick up a sock and it has holes, I throw it out. When the drawer gets empty enough it can fit another package, I buy one. What utility would come from worrying about when I used a particular sock?

I wear whatever makes me feel good.
