The Shelf Life of Most Medicine is Vastly Greater than its Expiry Date

We wrote before about shelf life issues in general, and pointed out that the expiry dates on most medicines are ridiculously conservative, and that it is common for medicines to retain full potency for many years subsequent to their printed expiry date – assuming they have been stored in optimum conditions. Here’s an interesting article that cites two studies of the extended effectiveness of medicines beyond their stated expiry dates. The larger study was conducted […]

Depending on the soil and your growing strategy, you can expect yields from about 1.25 […]

Shelf Life Issues, and Temperature in Particular

Nothing lasts forever – least of all, alas, ourselves.  But, if we can ignore that most relevant of all issues (at least for now), let’s instead look at how long any food item will last, and how can we give it maximum longevity. In a very simplified form, the life of any food item varies depending on a number of different factors.  Some types of food are more sensitive to some storage issues, others are […]
