I still occasionally marvel that I can wake up at 4:30am in Denver and be in Very Rural Virginia by 5pm...and that's with stopping over in Atlanta first.

It's not the travel, or the time, it's the 'it's more efficient to go thousands of miles out of the way due to logistics.'

This has not been particularly new, but I can still marvel at it.

Having fixed plumbing, I'm reminded that the current iteration is as a result of 2000 years of refinement.

I have a lathe, manufactured in 1966, it still holds tolerances, and I refer to a book (how to run a lathe) that's first printing was at the turn of the 20th century (1912 or thereabouts)

Old stuff is remarkable, too.
