Useful trivia

I came across this recently, and thought how very useful it could be; as long as one can remember it all.

I have tried it, and it is pretty accurate. The only one which was a bit off (for me) was the distance between little finger and thumb (bottom Left). Mine measured 20 cms, not 23; but maybe I've shrunk a bit.

Copy, print, and keep in your inside pocket/handbag. It's bound to come in useful, and you can thank me for it later.
