 It's absolutely true. We have a pail. It's like a six-gallon plastic pail that we have a 30-day kit. So for a person to eat for 30 days in one pail, it's watertight, airtight. It's perfect. You can just put it on a shelf in your basement, and it will last for 25 or 30 years. I gave those as gifts to my very large group of siblings.
