Do you have that friend who you think is smart and is curious as hell about how everything works? Well if by everything its the human body then this is the perfect DVD to give as a gift (Price: $14) . I love science, which is why I practice what I do, however this movie takes me a step beyond simple biology and chemistry. It brings in quantum physics and relates it to the human body and cells on the atomic level. A movie that I found fascinating while watching, yet more importantly, it left me thinking about a lot of things differently long after I was done watching it. I love thought stimulation and this movie did exactly that, for me. Again, like most things I enjoy watching, a background in the sciences will certainly add to the enjoyment, while a lack of it can end up stimulating something that has been dormant, a sense of curiosity that wont go away.
