What can I learn/know right now in 10 minutes that will be useful for the rest of my life?

How to determine which months are “short” or “long” for those of us who can’t remember poetry.

1. Make a fist

2. With your other hand count each knuckle and space in between while naming the months; starting on the knuckle nearest you.

3. When you get to the month you want, stop and look at your hand.

4. If you landed on a knuckle, 31 days. If you are in between, then 30. Or less.
