content: I have a few theories about this... 1) if you don't get enough sleep (at least 8 hours per night) your immune system is compromised. The less you get to sleep the worse your immune system becomes and it takes several days or weeks of good sleep to restore it to its full potential. The videos i posted from MedCram explain this in detail with proof and relative studies (links at the bottom of this post) 2) it is likely these doctors literally sacrificed themselves to save their patients, getting very little rest and not getting the necessary medical care even when they were severely ill, perhaps even to not add work to their already over-worked colleagues 3) maybe several of them got the illness at the beginning when little was known about it so they didn't get the appropriate medical care necessary to stop or slow down the virus in their bodies Beside this, even if you are not old and not sick, there is still a small chance that you are going to die anyways. Perhaps you just have many ACE2 receptors (the protein that the virus connects to to inject its RNA inside your cells) or perhaps you were exposed to too many virions (viral particles) in a small time frame, overwhelming your immune system and your ability to fight the illness. But even small chances, in large numbers, make several deaths that, of course, scare us because they stand out.  What is clear is that this illness is not a seasonal flu, it is probably at least 10 times deadlier, the real numbers are hard to calculate with the infection still in progress and with many asymptomatic or mild cases that are simply not counted because who is affected doesn't even go to the hospital. Freaking out though is of no help, we need to think about this rationally and take all the necessary steps to protect ourselves, our families and our communities. Here are some videos where MedCram talks (among other things) about the importance of sleep and how it affects our ability to fight illnesses. https://youtu.be/qqZYEgREuZ8 https://youtu.be/wlbM6VVkVZM https://youtu.be/vE4pBkslqS4
