Human Anomaly

I came acrosst his article that describes a man who supposedly hasn't slept for 33 years, without serious medical complications. I wonder how his immune system and brain have compensated for this lack of rest. I have a couple of questions about this: How many people would love to have this condition, to not be tired enough to sleep? and is this legitimate, can a person really go without sleep?
