Reply #9: True at one time, but NOT the case in the plastics used since the 1970s

Some of the earlier plastics would "leak" some of the plastics into any water the plastic was holding and you could taste it. Most such "leaks" were solved by the 1960s when even the US Army switched from stainless Steel Canteens to Plastic Canteens. The alcohol industry took longer, they did not start using plastics till the 1980s (With milk and water about the same time). Glass is still considered a more impregnable bottle, but plastics today are so close people can NOT tell the difference.

Another case of what was true at one time (1940s till the 1960s) is no longer true, but the old rule is still heard. This is similar to the old stories about Syphilis, if it was caught before it penetrated the water barrier around the brain (At about three months) Sulfa drugs and penicillin could cure it, but if syphilis did penetrate the the water barrier all these drugs could do was arrest it so you could NOT transmit it and stop most physical restrictions, but the well known mental problems that came with syphilis would still occur. I heard these stories as late as the 1970s, 20 years after Tetracycline was introduced (c1954) and its ability to penetrate the Brain water barrier and eliminate syphilis even in the brain. Old stories die hard, especially if true at one time (Even if no longer true). The same with Plastics NOT being used for long term water storage, not true since about the 1970s, but since it was true in the 1940s, 1950s and 1960s, the stories that water should NOT be stored in plastics are still heard and repeated.
