Circadian rhythms have fascinated scientists for many years. Recognizing that the eye nerves translate information to the brain about the time of day, scientists observe that we adapt to the conditions around us. Also, these researchers have recently discovered that not everyone is alike. For example, teenagers are nocturnal. That is, they are more active at night but do not function as well early in the morning.
