Manufacturers choose their "best by" and "expiration" dates....  I hate to suggest this... let me preface by saying the government should not have access to our private data and more than big-tech should....  but maybe the government needs a heavier hand with regard to such things for American industry.  When do things actually expire?   When are things no longer effective.    I have fungicides and insecticides with expiration dates of 15 years ago that still work as well as I can remember.  Should I still go out and buy new stuff yearly.  What about my lettuce seeds?  Is there a problem with me using 10 year old seeds, if they grow perfectly fine because I properly store them? The medical/insurance industries need more attention.  This may be a use for big-tech eventually (which will also require significant attention)
