68: “Put it back on the menu”

Didn’t Neil Diamond write that?

For all those years not divisible by 5, or otherwise significant (double numbers such as 66, 57 Heinz variety, 52 cards in a deck), remembering my age is sometimes a challenge. What does Wikipedia say about 68?

“It is the largest known number to be the sum of two primes in exactly two different ways: 68 = 7 + 61 = 31 + 37.” Now THAT is exciting. Isn’t it?

“68 is the atomic number of erbium, a lanthanide.” What?
“In the restaurant industry, 68 may be used as a code meaning ‘put back on the menu’, being the opposite of 86 which means ‘remove from the menu'”. I had never heard that.
“The NCAA Division I Men’s Basketball Tournament has involved 68 teams in each edition since 2011 when the First Four round was introduced.” And I’ve always hated those play-in games, especially the 11th seeds.

The photo, taken by my daughter on her phone, was for her Environmental Science course. Apparently, it takes 170 gallons of water to create that 750 ml bottle of wine.

Anyway, I don’t blog on my birthday. See you manana.
