I love statistics and figures.

The old 100% figure –  100% of us who are living will die.

The old 80% – 20% –  This goes for just about any volunteer organization.  20% of the people will do 80% of the work.

2/3 vs. 1/3 –  Generally the number of people needed to give permission for change is 2/3 or a group (the 50% concensus is usually problematic – the more the merrier!)

50% –  The amount of weight needed on each side of a teeter totter to keep things balanced (also goes for life in general)

7% – Good for GST, PST but quite movable depending on the will and whim of politician!

Got any other figures you would like to pass along??
