Snakes and Mice

On a remote (imaginary) island, there are 11 snakes and a single mouse. As you’d expect, snakes eat the mice. But contrary to what you’d expect, when a snake eats a mouse, it turns into one.

The snakes live by only two rules:

1. Don’t get eaten.
2. Eat mice as long as rule #1 isn’t violated.

How many snakes and mice will there be left on the island?

10 snakes, 1 mouse.

If there were only a single snake and mouse, the snake could eat the mouse, then turn into one, leaving a single mouse.

If there were two snakes and a single mouse, rule 2 would keep either of the snakes from eating the mouse to avoid being eaten themselves.

With three snakes and one mouse, one of the snakes could eat a mouse and be safe as a mouse thanks to rule 2.

This pattern continues. With an even number of snakes, nothing happens. With an odd number of snakes, one snake can eat the mouse.

Thus, with 11 snakes, one snake would eat the mouse, turn into one and leave 10 snakes and 1 mouse.

A Four Word Admonition

What four word admonition makes the happy person sad and the sad person happy?

The phrase, “This too shall pass.” According to Wikipedia, the well-known phrase is often attached to a fable of a great king who is humbled by these words, and to someone who is experiencing something wonderful, it can be saddening. But to one who is in the pits of despair, it is a phrase that brings relief and hope.

In other words, if a happy person is told, “This too shall pass” it will make them sad. But to a person on hard times, hearing, “This too shall pass” will cheer them up.
