How the body runs, what medicine can promise, and the psychology findings that survived scrutiny — carefully stated.
You are carrying around the most complicated object anyone has studied, and most of us know less about it than about our cars. These quizzes fix a little of that: what insulin does and where it comes from, what penicillin changed, how blood actually moves oxygen, and which parts of exercise and nutrition are settled rather than merely popular. The psychology here is handled with particular care. Several famous findings have not held up well under replication, so where a claim is shakier than its reputation suggests, the explanation says so rather than repeating the tidy version.
