I spent hours a day juggling for ~4 years in my mid teens (in my 30s now) and got up to juggling 8 balls.
I find numbers juggling (say 5 or more) to be almost therapeutic. It requires a reasonable amount of physical exertion, and it just pulls you into a flow state. All of your mental and physical focus is concentrated on maintaining this ephemeral pattern, and there's no room for anything else... until the pattern falls apart :-)
