When a computer becomes overrun with more information than its processor can handle, it crashes. The human brain responds much the same. Take me, for example. I recently wrapped up an ordinary day in the life of a third-year dental student. I had lectures in the morning and treated patients in the afternoon. On the ride home, something felt off. Everything I needed to get done was passing through my mind. I needed to study, finish lab work and prepare a treatment plan for tomorrow’s patient. Aside from school responsibilities, my wife needed me to get groceries. I got home, dropped my bag and knelt on the floor. All at once, those thoughts flooded my brain and I could not move. I just sat there, emotional and frozen.
