You and your family can travel on an amazing journey through the inner world of the human body. Have you ever wondered how your taste buds or vocal cords look at close range? How your eardrum processes sound? How are your muscles able to move in so many ways? Or how does your eye adjust to changes in light? Tiny cameras explore up close the internal workings of the human body in this crash course in human physiology. Though made in 1975, the visual effects created by x-rays, microscopes, and time-lapse photography still fascinate in this exploration at the microscopic level. ~ Gayla Mills, Rovi

I rented it for my 9 yr old who prepares for the science olympiads. He absolutely loved it. It takes very complex issues and shows it in a very vivid and interesting, but at the same time easy to understand way. I would highly recommend it to anyone who is interested in learning.
I believe there actually is a 1975 verison of this documentary but this obviously wasn't it. As for the content, it's somewhat interesting and educational but won't knock your socks off. There was really no need for me to look at Stephen Tyler's yapper for 20 minutes.
