Have you noticed that time seems to move faster as you get older? Well, that’s because it’s true. Our perception of time varies with age. Have people count out one minute and time them with a stop watch. Young people underestimate how long a minute is. Old people overestimate.
This video is part 2 of a four part BBC series on time. It starts out talking about our perception of time and morphs into a discussion about the possibility of immortality.
From the immortality segment: Aubrey de Grey thinks that after we have mastered the ability to stop the destructive processes of aging we will still only live about 1000 years. We’ll still be stepping in front of trains and falling in bathtubs, so accidental death statistics will become the determining factor for our expected lifespans.
