What golden nugget of wisdom did you learn that changed your outlook on life?

In the centre courtyard of the Pentagon, you don't have to salute superior officers.

It's a recreation and lunch area, and you'd basically spend the whole time saluting.

So it's not required there.

The source?

My uncle.

A navy corpsman who currently works at the Pentagon.

Stonehenge, the world's most famous henge, isn't actually a henge. A henge is a Neolithic earthworks, oval or circular in shape,

sometimes containing wooden or stone structures and surrounded by a perimeter of a bank with internal ditch.

So the famous stones of Stonehenge aren't even a

necessary part of a henge, just an optional extra. But more importantly, the bank and ditch

at Stonehenge are the wrong way around to make it an official henge. So Stonehenge isn't a

henge. However, the earliest recorded use of the word Henge is in reference to Stonehenge,

so non-henge, stonehenge, despite not being a henge, is the thing all other henses are named after. If you don't have a toilet plunger and you've clogged your loo up, pour in a bit of dish soap and some hot water, the hotter the better, let it stand for 15 minutes and flush. Learned this way when I realized upon

arriving at our hotel that my eight-year-old had clogged up our loo and I googled it. Found this gem,

realized I'd packed a tiny travel bottle of dish soap, warmed some water up in the microwave,

and lo and behold, it worked. I still use it sometimes at home when I don't want to be grossed out

by plunging. Yes, my child still has a tendency to clog toilets.

So there you go.

X percentage of Y is the same as Y percentage of X.

So if you're struggling to find 26% of 50, maybe 50% of 26, which is 13, is much easier to do quickly. Control shift escape opens straight to

the task manager instead of control alt delete and then manually selecting task manager.
