Non veni pacem mittere, sed gladium.
I question how seeds can remain viable for more than a couple years.
Some very old seeds have sprouted- here's a 2000 year old date palm:https://en.wikipedia.org/wiki/Judean_date_palm#Germination_of_2000-year-old_seedI've gone to seed too, and wonder how long I'll be viable! Bet I won't last 2000 years though....
That's funny. Probably is a good idea to renew the can periodically, but keep the old one. Seeds, whiskey and .22 ammo will be the new currency in the burning times.
