Tell me, first of all, if you would, a little bit about ReadyWise.

And this is a small red waterproof bag all tied up and ready to go.

Because a few years ago, we used to think of this as quite a niche product that only a few people with a certain mindset maybe would have a need for.

It's quite convenient having this freeze-dried food, but you do still need a clean water supply to make it work.

How do you see this market expanding?

The range of people buying this has changed a lot, even in the last few years.

Is this going to become an everyday thing that everybody has?

Now, that could be the answer, but the ReadyWise bag that Kim showed me cost around $120.

And if you want a year's supply, well, that would cost you more than $3,000.

So you might be thinking, what sort of person would be that committed to prepping?

Is this still a thing that perhaps women don't consider as much as they should?

What is it that scares you the most?

Is it a natural weather disaster?

Is it some kind of conflict?
