I don't want to lose weight for vanity. I want to live beyond my 50s.

I forget the exact statistic, but it's like a spoonful of botulism toxin can kill millions of people. It really is potent.

But the difference between poison/toxin and medicine is often just dosage. There are myriad, countless medicines to discover in toxins. The toxin of an animal for instance a snake, is not one toxin, it's hundreds, each with individual action.

There is a reason the ancient greek symbol for medicine has two snakes on it. Anyway here's an old article on it in case anyone is interested.

And fentanyl can kill an entire city, but hospitals still keep it around for pain control. Diphenhydramine will make you hallucinate spiders everywhere, while you slowly die.

Dosis sola facit venenum, as the medical world likes to say. “The dose makes the poison.”
