    Wow, this is very virophobic. I thought NPR was pro-migrant? So-called "viruses" are oppressed minorities fleeing their war-torn homes, looking for a better life.

    I just wish that proper terms for the processes and proteins were used

    I’ve have the flu before and survived without a flu shot! I was very luck and relieved that I didn’t die!

    The WHO recently listed pandemic flu as a leading threat to global health in 2019!

    I'm convinced that cells have some degree of sentience in them, much like the concept of Midi-chlorians.

    The human body is like an office block or factory with different departments, full of staff, doing specific things for the whole 'business' like waste, catering, power, HR, security, stock control, rotas, maintenance, etc, etc.

    The main flaw or question (depending on your opinion of my hypothesis) is, does this mean our thoughts and actions are not directly governed by ourselves, instead being a variation of how your body (or your branch of the conglomerate known as 'Humans Ltd') operates in the same way different branches of a supermarket does things slightly different to other branches?

  17. Igor March 20, 2019 at 11:24 am

    not millions and millions but 500 to 1000 viral particles coming out of a single cell (for influenza). that's called a viral burst size
