No Panic. Just good planning.

Now, this is a time to get those things you put off, done and out of the way. It's a time for reflection, thinking of others, contacting old friends on social media. Time for yourself to start new hobbies, read more, talk more and plan better for future times like this.
Take advice from the government regarding the virus and stay safe.

It's good to have a store cupboard and medicine chest with essentials ( keeping checks on dates ) saved for a rainy day and good too, to get yourself a plot of garden ready if possible, for harder times ahead. Also, it's great to just eat fresher and tastier vegetables. WE do never know our future problems but knowing you're ready for most eventualities is good.
Panic buying is bad for all concerned. Firstly the people that cannot compete for things are left high and dry. Shops make a killing and put prices of essentials up massively because they can. You leave stores looking like they had a plague of locusts descend upon them. For the most part, this ends with rationing, shortages and queueing. The sad part is most people become just out for themselves not thinking of the bigger picture.
So relax try to be better prepared for a crisis, you can be sure there will be one, it's just a matter of when.
