Pretty sure that diluting red wine until there are trace amounts of it left robs it of any beneficial properties of the antioxidants it contains, and it definitely doesn’t increase their power… So we’re not really talking about homeopathy which is the ludicrous belief that massively diluting something actually increases its potency.
Yes diet and exercise can have an important effect on the body, and yes the placebo effect does exist but:
i) the plural of anecdote is not data;
ii) as f***ed up as the US healthcare/pharma system is there are hundreds of thousands of academics and public sector doctors and health researchers in other parts of the world who have dedicated their lived to finding proven cures and treatments for illness using the scientific method (you know, that thing that made smartphones, computers, the internet, VR, space exploration etc etc possible). They are not profit driven and they don’t get kickbacks from pharmaceutical companies and they are putting their lives on the line to treat this epidemic;
iii) Countries are losing billions (if not trillions) because of the economic disruption caused by the coronavirus and are resorting to unprecedented measures (including looking at ways to convert car plants and other factories to produce medical ventilators). If curing or preventing coronavirus was as simple as drinking some silver solution, turmeric, powdered bleach or whatever other alternative treatment du jour is circulating on the Internet today don’t you think that at least 1 of the countries currently in the grips of an epidemic would be using it???
Seriously people need to develop some basic critical thinking skills.
