    No I just have a wider perspective on definitions than what is commonly used.
    The phrase "Natural Selection" does in no way point to procreation . It points to "selection by natural means".

    The virus is a perfect example. It is very successful, not because it can reproduce, but because it can use the host's reproductive abilities to multiply.

    Natural selection: the process whereby organisms better adapted to their environment tend to survive and produce more offspring.

    Words mean things.

    If a mod is reading - can we bring the different coronavirus threads together under one? Thanks

    Means natural selection, no more , no less.
    Words mean things. If you want to add to the meaning of words then you add that additional qualification as you just did. And then you end up with the full definition of "Evolution by Natural Selection."

    So viruses depend on their hosts to reproduce, no? When the host develops immunity, the virus dies because it is unable to reproduce by itself.

    p.s. I read that viruses and bacteria may have had a common ancestor, but that the bacteria evolved into greater complexity and the virus devolved into simpler complexity.
    Both ways must have been a result of natural selection, no?

    An interesting tidbid. In several Eastern countries they are using infrared scanners on large crowds to detect people with elevated temperatures , which are immediately removed and tested for infection.

    In the US we could use marihuana spotting helicopters for the same purpose. This sounds an excellent scanning system for large crowds. This has been used in the past, but I haven't heard of it for the coronavirus

    Wrong wavelength, and it doesn't work outside.

    A drone over a stadium or large gathering might be very effective in spotting fever elevated body temperature. I thought it was extensively used by the military.

    I did. That's why I said wrong wavelength. In addition, it does not work outside.

    OK, I'll accept that marijuana cameras are not suitable. What about military infra red drones or the scanners which are used in the other examples I cited?

    They will work well in indoor environments. Not really outdoor environments for several reasons.

    Just saw Bill Maher talk about sativa. His guest remarked that she liked the feeling of the smoke in her lungs.

    This brought to mind how that might affect the Coronavirus which specifically attacks the lungs.

    Had a vision of a bunch of viruses lying about stoned, and forgetting to become virulent....

    I wonder if there is a form of say alcohol , or one that can created , that can be carried by a molemecule , into the blood stream and bind only with the covid-19 virus , to suck the water right out of it . But not to surrounding healthy cells .

    So this molecule , it doesn't enter the virus , rather it sucks it dry . From the outside . Hence the virus becomes shriveled up and dies .

    Don't know if this is possible .

    Just saying .

    The Corona of the virus refers to these nodules that stick out from the virus its self , which is used to bind to the cell it wants to infect .

    Which means that , these nodules at least communicate with the core of the virus . if we go through the middle of these nodules past the membrane of the virus , we could draw all moisture from the virus .

    That's how regular old soap and water can kill the virus on your hands - it messes with that viral shell which is made of fats. The fat - loving end of the soap molecule sticks to a chunk of the fat in the viral cell wall, then the water - loving ends sucks the combo back into the water surround. After a while the viral shell looks like Swiss cheese, the guts leak out the holes and it is dead. (ceases biologic functionality)

    Those little receptors in the corona really like angiotension type 2 receptors, especially those in the lower lungs, heart and vascular system. If you a male and have been on an ACE inhibitor for high blood pressure for a long time, your lower lungs express many more angiotension 2 receptors than normal. (Don't know if it's the same for women and it doesn't happen with ARB's.) This over-expression appears to lead to a major increase in risk of developing viral pneumonia from C - 19. That leads to a systemic infection that takes out your heart, kidneys, liver etc and you die.

    On the flip: they are experimenting with giving ACE inhibitors to folks that haven't been on them and have C - 19 in the hope of robbing the virus of host cell targets. No results yet.

    If you are a smoker/vaper you are some 14 times more likely to get a severe case of C 19 if you catch it. If you are immune-compromised (*raises hand*), genetically - predisposed, or just a little out-of-shape, C - 19 wears you down until you get regular old bacterial or mycoplasma pneumonia. I rather suspect that is why a Z pack is helpful for some folks.

    It is my understanding that once those receptors fully engage with the angiotension type 2 receptors on the target cell, they inject that cell with messenger RNA. That RNA makes its way to the DNA core of the cell, joins with it, and instructs it to do nothing else save make copies of the virus until the cell is so full of those that it bursts open and dies.
