That’s not what I was implying at all I have no clue how you arrived at that. I’m saying an LD1 does exist – it’s the dose that would be fatal to 1% of a population (and further a LD0.1 and 0.0001 exist). These doses are lower than the LD50, fatal to millions, and approach what some would consider normal. For instance: https://www.nbcnews.com/news/amp/ncna759716
