Alejandro Rules

In tennis, this rule comes into play when you're leading by just one game and want to avoid the risk of losing. Under this rule, you play just one final game, with no possibility of losing. The result will either be a win or a tie. var: "Super Alejandro" rule: You're up by more than one game and can only win.

Momentum changed and I won 4 in a row to get within one game, but my opponent invoked Alejandro Rules and it ended in a tie.

Rule of 72

If you don’t practice something hard in 72 hours (3 days), you will forget it

It’s Sunday. I haven’t practiced the Rubiks Cube since Wednesday. I sit down and think: How the hell do I do this thing? Then I realize I haven’t practiced in 72 hours. I think ‘Oh... Rule of 72.’
