Scientists believe that we can find the answer from fat-tailed lemurs whose genes are very similar to those of humans. Researcher chris smith believes that fat-tailed lemur primates have incredible characteristics, and hibernation is a way to prolong life. Smith believes that if some seriously ill or terminally ill patients are put into hibernation, their breathing will be reduced and their heartbeat will be reduced, so they will have more time to wait for organ transplantation. It is understood that Allen, a researcher from the University of Chicago, began to study deep sleep from 1989. The results show that although deep sleep is more conducive to deep space flight, hibernation technology can also promote the extension of human life to a certain extent.
