Jeff, our resident genius here at Southampton University, just pointed out to me something I had overlooked all of my life. By utilising the position information inherent in your fingers (they are in a set order), you can use them to represent binary digits. As you have 10 fingers this means you can count from 0 to 210 - 1, 1023, ON YOUR FINGERS!!!
Previously I had only been able to count up to 10, so Jeff has increased my counting capacity by a factor of 100!
This is, by far, the most important thing I have learnt all year. Please, tell your friends. Pass on the joy.
P.S. by bringing your toes into the mix, you can count to 220 - 1 = 1048575!!!
