Wired on Youtube has a fascinating playlist on their channel where they get different experts to go over the answers people ask them on Twitter. (They are still calling it Twitter, not X as Elon Musk has decreed).
Humans are inherently curious beings, so when given the chance, they do ask. One of the most popular expert episodes is the one with the mortician. Also popular are the episodes with a lawyer, a human geneticist who answers DNA questions, a pulmonologist (lung doctor), a former CIA Chief of Disguise, a forensic scientist who answers crime scene questions, a coffee expert and so many others!
