On a scale from "cell phone 'radiation'" (nil threat) to "kids playing in asbestos snow" (extremely serious threat), what does the existing evidence indicate is the level of concern we should all have about these kinds of plastics re: human health? Is it really still a complete mystery, or do we yet have some level of certainty about just how bad it is?

Will we sheepishly have to explain to future generations "that's just how it was back then, plastics were everywhere, sorry about your cancer", or is it overblown at all?

I would ask you about the least traceable way of starting an electrical fire, but instead I'll ask: what was one of the most successful ways to get away with starting an electrical fire in the past that you'd never get away with nowadays?

After a recent shrooms trip, which went well for me, I experienced a significant headache which continued for the rest of the day and into the next. Looking into it, I found that this is a common side effect for others, as well. I also learned that the inventor of LSD had actually been trying to find a cure for migraine headaches, but both shrooms and LSD actually commonly cause headaches. Since the brain itself obviously doesn't have pain sensors, can you elaborate on why psychedelics might frequently induce headaches as a side effect?

What do you think will be the most likely macro-scale applications for quantum forces like the Casimir effect?

Thanks!
