Why is it that whenever there is an infectious disease such as SARS and new crown, when humans trace the source of infection, they always point the finger at bats?
There is a general rule in mammals, the smaller the size, the faster the heartbeat and the shorter the lifespan. And the alien out of the flight suit, the bat, somehow hacked into the genetic system millions of years ago, so that it could complete the chromosomal telomeres and let the cells divide indefinitely, although it was as small as a mouse (mouse heart rate 500 / min, life span of 2 years), heart rate as high as 1000 / min, but has a lifespan of 40 years. High heart rate brings a body temperature of more than 40 degrees, and high body temperature means that the virus activity is greatly reduced, the immune system activity is greatly improved, so bats have a super immune system that is invincible, even the Ebola virus known as the "human curse" can fully break the immune system.
Moreover, having unlimited cell division ability can also make it recover quickly. In this way, the bat sealed all the viruses in its own body and slowly cultivated the clams. The social nature of bats also contributes to the risk of cross-infection of viruses, resulting in the evolution of new variant viruses, Ebola that has only appeared in Africa, and actually spread across the ocean to bats in the Philippines, and there is a mutation.
Humans do not have the immune system of bats, and bats do not bring blessings to humans. So, cherish life, far away
Away from bats.
