Hormones
Hidden Messengers
Hormones influence our lives. Just like our nervous system, they transmit information in our bodies. When our hormonal balance is disrupted, our behaviour changes and we may fall ill. But what are hormones? Why have they got such a big influence? Where are they produced? And how do they work? The film leads us inside the human body – into the world of hormones. We learn that there are various hormones, where these are produced and how they work. We get acquainted with people whose lives have been influenced by a hormone deficiency or a hormone excess.

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
