I've been watching videos about identifying food, medicinal, and poisonous plants. There is a world of informational videos on Youtube.
One thing I saw on a show that I hadn't thought of is if you are sheltering in place (staying in your home), to make your house look like it's already been looted if that is going on. Throw things out in the yard like it's been trashed and don't give off any signs of occupation.
I talked to my oldest daughter today and asked if she had an emergency plan and she suggested something that I was going to suggest... that all the kids and grandkids go to their father's (my ex) rural home. Get out of cities for safety and away from a lot of people in case of pandemic.
I am part of my employer's Corporate Incident Response Team (CIRT) for the communications systems so my first shelter choice would be the secure building.
I worked as a certified nurses aid for years but I could stand a refresher since that was probably 20 years ago. Out of shape here, too. :-D
