    If at first you do not succeed, try and try again. Then dig the manual out of the garbage.

      Have heard that pharma companies deliberately underestimate the expiry date on their medicines; however, not sure of how low/high is their 'factor of safety'. Factor of safety = similar to how civil engineers design the dimensions of their structures, with a 'factor of safety'.

      Pharmas conduct stability testing on their drugs, which under very carefully controlled conditions determines how long the active ingredients remain effective in the recommended/expected storage conditions. This data determines the BBD, not the desire for increased profits. Obviously there's a deliberate tendency to err on the side of caution, because it's in no-one's interest to have people consuming ageing drugs that no longer work as intended.

        In my first university level programming course, the professor introduced the concept of algorithms using the instructions (a.k.a. "manual") on his shampoo bottle: * Wet hair * Apply * Lather * Repeat Actually, the manual was very useful for learning the basics of algorithm, and precision of description. He made a big issue of points such as 'Apply' - the whole bottle? Where should it be applied? what does 'Apply' mean? When he got to 'Repeat' (the first time), there was no indication of what to repeat, so he tried to repeat it all. But he couldn't 'Wet hair', as it was already wet! He reached 'Repeat' a second time, and a third time, and a fourth time ... The hot water tank ran empty, and his shampoo bottle ran empty ... So silly manuals / instructions can serve a purpose, although not necessarily the way the manufacturer intended. A similar experience: A couple of weeks ago I spent the last grains of salt in that 1 kg box. Before I threw the empty box in the garbage, I noticed that it had a 'Best before' date. For table salt?? I consider sodium and chlorine rather stable elements, and the bond between them as well. I would never expect the potency of either to decay much with age. My new box of salt also had a 'Best before' - three years into the future (2027). The old box was expired by two years (I do not use much salt in my cooking), so it was probably bought five years ago. The last few grains had started lumping together; I guess is the reason for the BB date. Not really "best before", but "may start lumping together after 3 years". I know to store salt in a dry place, so for me it took five years. I guess referring to the date in your wedding ring as the BB date can be considered an NSFW joke inappropriate for the Lounge, so I suppose I should leave it out.

        Salt is good at collecting humidity. And anything coming with it. Living things are not much a problem, but all else can be.

          But do you really want to be the one that signs up for the study that determines that the medicine you have been taking for your condition is not actually working anymore?

            Does it include the warning to "always keep away from children"? Which I find nigh on impossible with 10 grandchildren.

              Maybe then, the placebo effect takes over. "I have taken the medicine, and it's working".

                Probably one of the Xaar heads: when I was working with them the droplet volume was either 40 or 80 picolitres* depending on the head you used. And none of the distributors could understand that the amount of ink you used per print depended on what characters you printed ... "i" used a lot less ink than "W" :D * I got "picolitre's", "kilometers", and "picolitres'" as corrections.

                Interesting. My company builds commercial inkjet printers. Our drop volume ranges from 6.5 to 13 picoliters, depending upon the product.

                  (my emphasis.) I have a memory of some ink jet printers boasting of variable size droplets: The physical resolution was 300 dpi, but rather than dithering a 600 dpi output, you got 'true' greyish, or less saturated colors, with smaller droplets. I actually thought that this was a standard feature on ink jet printers, but I know no more about them than the average customer (or at least average programmer). Maybe the technology of variable size droplets failed. Maybe it couldn't be used with some dyes for color printers. I don't know. Or maybe the inkjet printers of today do use variable size droplets.

                    Some placebo is so strong that it works even if you don't believe in it.

                      While we do adjust drop size to an extent on-the-fly, it's more for ensuring drop uniformity than achieving different color intensities.
