Why our sense of time speeds up as we age

Researchers called this “time pressure,” and it goes hand in hand with stress. It makes sense considering the other theories, too. The more stressed we are, the less likely we are to be focused and present on the moment—we’re just trying to get through the day as quickly as possible. When we do that, we don’t have time to take in our surroundings and build detailed memories. Thus, our perception of time flies.
