It is difficult for people to believe that sleep can help us get eternal youth and cure diseases

I recorded a video trying to explain that we can get eternal youth simply by sleep. But nobody believes it.
The link to the YouTube video is:

I tested the method myself. The least it can do is give me great sleep that makes me feel good all day.
Time will prove the correctness of the method.

I hope more people will benefit from the method.
