Nice job! I am very skeptical of people who claim to not need much sleep.

We know there have been some who really needed much less sleep but they are widely known to be geniuses or hyper-productive (Nikola Tesla, Elon Musk etc.)

Most people who claim to sleep only 2 hours a day or whatever are probably being a little dishonest or are miscounting.

I don't buy this. I don't know life of Nikola Tesla, but the recent activity of Elon Musk might be explained by a serious and chronic lack of sleep.

Short Sleepers certainly exist, but they're rare. https://www.ucsf.edu/news/2019/08/415261/after-10-year-searc...

But I've usually heard of them needing ~4 hours of sleep, not 2.

I had a teacher in high school that was like this. He got a job as a night checker at the grocery store to help pass the time and make a little extra money. He felt great when getting about 4 hours of sleep. He had researched it quite a bit and after talking to a doctor decided to embrace the extra time. I was always jealous.

But yeah I don't buy the 2 hour sleep thing, because according to this teacher it's almost always around 4 hours for people in this boat.

Nikola Tesla was certainly not for not being entirely sane, so that might be evidence there as well.
