Sure, it works, but I don't get why. Simplified, it means that 117 minus your age equals the year of your birth. Or you could also say that 117 minus the year of your birth equals your age. Or that the year of your birth plus your age equals 117.

But where does the 117 come from? What's so special about the number 117?

Please explain, someone.

if you're over 77 it's minus 40 instead of plus 40.

Works using this formula.

Oh... wait... It's because we're in 2017! In 2018, you'll have to add 78 bottles of wine (or raise 40 to 41). But tatsfield, 77 minus 91 equals negative 14, and when you add 40 to that, you get 26 (for the year 1926), so the formula still works... I think...?

I worked out DH - he is 78, so taken from 77 = minus 1. TAKE this from 40 makes 39. he was born in 1939. I am 75, take this from 77 =2, ADD this to 40 makes 42, I was born in 1942. I don't care what year I was born - do a get the wine as a prize ?

A logical mind amazes me. Mind blown! I try to avoid math....
