I was home schooled, so I was never taught science in depth. I'm interested in learning about human physiology, health, and such. Can anyone recommend any good resources for a casual learner? Lectures, videos, and documentaries are more enjoyable; but if there's a particular textbook you think is useful, or if there's a subject that really needs in depth study, I'm more than happy to read it. In case I'm not here to reply, thanks in advance for your recommendations.
