pretty sure i read an article a while back that the US military in the 60’s or 70’s did a review of medicine stocks and realised the expiration dates on a lot of them is total BS.
also for some light entertainments...have a look on youtube for the MRE reviews.. particularly stevemre (i think thats his name, search youtube for ‘steve mre’). he is hilarious as he reviews stuff all the way back from ww2. obviously some is unedible but you would be surprised...
remember this ‘lets get this on a tray...NICE’. trust me if you watch 2 or 3 episodes, you too will see the humour in it..
While I was serving in the Navy in about 1962 I was working on evaluating and reconditioning old life rafts on my ship. We found some WWII vintage emergency survival ration packs from the early 40s. Cans of a Spam-type meat, crackers of a hardtack substance, soft candies and 10-packs of cigarettes.
Everything was still edible, and the smokes were potent.
