What exactly does it mean \"clean up\"? In what sense? Love a little more detail on this one. Thanks.

Dear JRegis,\n It helps you lead a healthy, active life style. It helps you have a more pro-active, aggressively set, outward personality. So, say, for example, some mouthy punks meet you on a Saturday night? Say you been listening and doing the changes? You are now bolder and it shows. This gives you an idea what this file means, in action, in effect, on yourself.\nSincerely,\nHaxsaw
