Dogfish head 90 minute aged for 3 years in a Sam Adams utopia barrel from 2019.
Not the most expensive thing I've drank but it was the most expensive beer I paid for.
I had gotten a 1 gal refillable mini keg filled from a local distributor and went back the next week for another so I'd say it was worth it.

My smart watch recently died and I found myself quickly glancing at my bare wrist then surveying my surroundings for a clock only to check my phone as a last resort. Before my smart watch, my phone was my default but I'd still see clocks, read them... and then check my phone immediately after.
Things like flyers, posters, communication boards etc, have completely blended into the scenery for me for as long as I can remember. Unless the active task is waiting with little to no distractions or entertainment I won't notice them.
