Some people require less sleep than others.
If you’re not a morning person, you might be able to blame genetics for not blessing you with “basic helix-loop-helix family, member e41 (called BHLHE41 or DEC2).”
This rare gene allows you to cycle through the sleep process faster than others, meaning you simply need less sleep.
Margaret Thatcher, Salvador Dalí, and Nikola Tesla all had this gene.
Imagine how productive you might be if you didn’t need as much sleep as you currently do!
I’m not saying you could become a great artist or scientist…but I’m not not saying that, either.
