It is also a matter of how you feel your time. The people in Germany and USA, especially in big cities, are stressed all the time. The more stress the faster your time will run. In NYC people are so concerned about their time, they always say I dont have time, in a really extreme matter. I also wondered why they think like that, because in Germany we also have stressful work and a long distance to ride to the office. It depends on how you feel the time. In addition n, my life experience says that the older I become the faster the time runs away. The reason for that is the brain. I learned that in psychology.
