EDIT: Ruthless made a good point of putting rules, so here they are:
1. You have to watch AND listen.
2. You can only sit on a small wooden stool.
3. You can't get off of the stool or stand up until all 24 hours have been watched.
4. You will only be given Vegemite and extra fiber whole grain bread to eat.
5. You can't drink coffee or any other energy drink. Just water.
6. You can only use the restroom once every 2 hours.
7. You can't fall asleep.
