What Are the Super Sleepers?

There are some people, a very small percentage of human beings, who can do very well by sp with very less sleep. So some world leaders have have had this characteristic. I hear that margaret thatcher, the former prime prime minister of the uke, was able to perform very well on four hours of sleep. She would sleep just four hours and then wake up and go back to work. And i hear that even our prime minister, mister mody, is able to function very well on 4 hours or so of sleep. But most people need at least seven to eight hours of sleep,. That's just how it is on average.
