Some bad things:

1. When you are unable to sleep.
2. When laptop battery indicator lights contribute to 1.
3. When there are chocolate wrappers on your floor.
4. When there are enough of 3 to be the most obvious solution to 2.
5. When 3 is probably the biggest contributor to 1.
6. When blogging becomes more reasonable than trying to solve 1.
