Capsu78, could you go back and use the URL feature on that weblink? It's so long that it makes this thread hard to read without scrolling left and right for every line.
I think others will cover the usual preps, like food, water, shelter, masks, etc. Just another angle. Do you have health insurance? Do you have disability insurance, both short and long term? Do you have enough cash reserves for at least a few months of mortgage payments, bills, and other living expenses? Do you have a will and other arrangements in case the unthinkable happens? Who will take the kids? If your kids' usual caretakers (like you and your spouse) become too sick to take care of them, do you have people you can count on to take them? Do you need life insurance?
Just some big-picture issues that are often overlooked when thinking about preps, but with similarly harsh consequences. E.g. if you lose your job (you refuse to go in, the company goes under, etc.) then you have no income and then what about your house/apartment? Or you get sick and you don't have health insurance to pay for the ICU and such? Again, maybe lose the house. Or you have a job but get deathly ill and even if you survive, it takes weeks or even months to get back to 100% No work usually means no pay, unless you have disability insurance.
