Concerning Behaviour.

Coffee consumption: moderate amounts is fine. But what if you have to go to the toilet four times during a three hour exam because you couldn't sleep the night before and therefore was more than a little bit worried you would fall asleep over the test paper? What if, at random times in the day, you just cannot stop shaking due to the excessive amounts of caffeine in your body?

Bad judgment calls: everyone makes bad choices, everyone makes mistakes. But what if you you don't trust yourself to make any of your own decisions anymore? What if, every time a judgment call needs to be made, you would prefer someone else to make it for you, because you are sick of making bad decisions?

Lack of concentration: everyone says they can't concentrate, to some extent. Often in regards to study, or listening in lectures. But what if the lack of concentration extends to all areas of life? What if, you find yourself crossing the road, suddenly realizing that you didn't even look at the lights or check for cars? Or, if it is only 30 minutes into your haircut you realize someone is cutting your hair?

There are times to react.

There are times to be concerned.
