my motto (till i find a better one) "watch the handle" apply as you want.
i came up with when i was bored at work throwing a very large kitchen knife in the air and catching the handle (very sily thing to do really). i use it to remind me to observe everything and be very catious, knowing when to snatch out and move and when not to.
its just about observation really.
