I don't know about short sleep gene, it's the first time I'm knowing of it. Although I've heard about people who have natural low blood pressure, and it doesn't affect them, I don't know of people with short sleep gene..
It's weird what the body of different people is capable of, my own condition is a spin-off of nature trying to protect the system from Malaria, and now a full blown gentic conditions is born out of it. It's just truly saddening.

Health can't be exchanged for money, and if you are sick and unhealthy all the money in the world can't fix it. That might be different in 100 or 200 years when aging is deleted from the human genome. Way too late for us though!

Under it can't, many will not understand this until they actually lose it. It's baffling how people underate or abuse what they have for free, thinking that they can make up for wasting their good health when they finally have all the money.
