To me it's not about the shortage only. I do not frequently shop since I do not like it plus do not like crowds.
I always had a pantry. It was easier as I worked and now it's easier for me and my children if I get ill. I want them to have enough food if something happens to me.

If enough people get ill there will be a shortage. Why? Because you need people to deliver it to shops, etc.

I wish you good health. 💕
