If you had to spend 3-6 weeks homebound, literally not leaving at all, what would you need? Include the usual over-the-counter meds you might normally use in the course of a year.

Then, if the economy tanked as a result of an epidemic, for 3-5 years, what would you wish you'd bought beforehand?

That's about all you can do.

Remember, if you're homebound, you'll really want to exercise after a few days. Some way of doing that indoors is wonderful.
