re: Ingesting Toxins
Many studies have shown that a small amount of alcohol on a regular basis (a glass of wine a day) is good for many aspects of your health. Heck, I probably don't drink as much as I should!
Oddly, it's been shown that small amounts of radiation are also good for you. It's called hormesis. Unfortunately, many regulations assume that the health problems vs. amount of toxin graph is always a straight line.
