While I wouldn't recommend going full doomsday prepper, I do think it's a good idea to stock up on food and provisions. A few weeks, few months, whatever you're comfortable with. Whether it's lockdowns or a global recession, I believe we're in for some tough times before things get better.
Just by the very nature of how this thing spreads and infects, containment is impossible. A vaccine, if there truly is one, won't be available for at least a year. So I believe the best we can hope for is wait it out and let Nature do it's thing until it corrects itself. Whether that comes in the form of Covid-19 mutating into a lesser problematic virus, or the virus burning itself out, who's to say.
I just don't wanna see some of you guys stress yourselves out over this to the point where it's taking a serious mental toll on you. We've gotten through pandemics before and we'll get through this one. Humanity has always been highly adaptable. That doesn't mean this year isn't gonna suck. But all you can do is prepare as best you can, take care of your health, and move on with your life.
