This is a clip from the BBC series “Time”, investigating the structure of time and how we perceive. The quote is placed between an experiment where a man in free fall manages to read a number that flashes faster than, what the human eye can detect. Thus proving that under the influence of adrenaline, the time can really slow a man. At the same time, in a laboratory the scientists experimented on rats by using other drugs known for similar properties, namely cocaine and marijuana.
