Honestly, the best thing anyone can do right now is look after their general health.
Overweight? Fix that shit right now. Cut calories, exercise. Don't listen to anyone saying you're "losing too much" or "losing too fast" as long as your BMI is above normal. Don't @ me over BMI being unreliable, it's good enough.
Take a multivitamin, maybe take a lil extra vitamin D, especially if you are indoors a lot.
Personally I hope that karma is a thing and that it bites the hell out of some of the folks in charge of this shitshow.
