On expiry dates, and shelf life.
I am never too certain of it.
Typical examples are medicines.
For example, ships hospital has every medicine, for everything. On the other hand, seamen are generally healthy people, under annual medical fitness certificate.
So, medicines on board are not used in great quantity, or used rarely.
When they expire, they get replenished to full inventory again on annual basis to get medical chest certificate. Replenishing entire hospital is expenisve exercise
It is unthinkable in modern day that somebody is given expired aspirine! God forbid! (he might die, or he could sue?)
Then I remember a story of "last ivory hunter" (Wally Johnson) book written by capstick.
He injected him self with expired antivenom serum after being bitten by gaboon viper and survived, One of few ever bitten by that snake that survived..
Then I remember war in Croatia
We were getting all kinds of aid, including European medical aid and medicines, and including expired medicines from old stocks. in large quantities....
Nobody complained.
People were treated, and survived.
I asked my mother about that (PHD Neurologists, chief of staff), she said no issue, All works.
Oldest ammo I've been firing was milsurp, vintage 1953, Works.
Then we come to modern ammo and explosive artillery ammo, shelf life and low stocks
I have doubts on shelf life. Expiry dates are convenient and profitable for industry. it keeps production alive, even without consuming.
Expired things must be replenished.
I am not a doctor or pharmacist, but from what I understand expired medicine can lose some of its potency or effectiveness. But for the most part it still works pretty well. And obviously its way better than nothing.
But what I have noticed is that people want the best and greatest and nothing else. Even asylum seekers or refugees. In Toronto on the news today there was a sob story about how some asylum seeker had to walk from Pearson airport to a shelter on peter street (about 25km). Once he arrived at this shelter and saw that people were sleeping on the street he supposedly developed a mental health issue and is now roaming the streets. Now having to sleep on the street for a week or two and walk 25km isnt particularly fun but if you are an asylum seeker, meaning you are fleeing your country because you are facing severe persecution like your life being danger, wouldnt you just be happy you arrived in a country where you are safe.
Another interesting thing Ive noticed is a lot of these asylum seekers are able to pay for $2000 plane tickets to come to Canada. They are also wearing brand new Nike sneakers and so forth. But they have zero $$ on them in Canada. Very strange.
