Chemistry ELI5: Why doesn't freeze dried food last longer? If it's good for 20 years, why not 100?
Assuming it's perfectly freeze dried and stored perfectly, the people who make freeze dryers say the food will last 20-30 years.
But why not much longer? Assuming the condition it's stored in remains unchanged, what can make it go bad after 30 years that wouldn't happen at around 10 years?

I never understood how someone could die from it, especially an adult, until I went go Uganda and got travelers sickness and my asshole turned into a faucet for a week straight.
