FWIW, I have noticed a dramatic change in my own illness response since supplementing with D3/K2. Even struggling with autoimmune issues, my chances of catching something were smaller. When I did catch it, it was much less overt ugly symptoms, and much more just tiredness, with rest the best thing.

Right now I'm working at home, and also, working ahead. If I feel like I'm coming down with something, I'm going to take sick time so I can rest. It's an ironic side effect of the social distancing, shuttering of businesses, and so forth: everyone has time off. This might help people dodge the worst, personally.

But I cannot emphasize enough that the US Federal Government needs to come up with a plan to keep us all functioning in place, or the economy will fall down and can't get up. People without an income right now need help.
