It is common to hear people lament that time seems to go ever faster the older one gets. I remember lazy summer afternoons, when the days seemed to stretch out forever. As a kid I would spend summer days waking and scavenging for ripe raspberries in the garden before checking the pool to see if the water was warm enough yet for a swim. I would stretch out in the grass or the concrete and look for shapes in the clouds, go on long bike rides with my childhood playmates, find insects aplenty and catch fireflies at night. Long conversations, plenty of daydreaming, listening to crickets and noticing the smell in the air as a thunderstorm approached. Some days felt interminable. The schooldays likewise felt incredibly long, watching the seconds pass in math class, doodling in my notebook as we learned about the U.S. Civil War. Then at a certain point, things seemed to speed up. Routine crept in. As we approach the start of 2026, I feel that January 2025 was only yesterday.
In Felt Time, the concept of subjective time is unraveled by German psychologist Marc Wittmann, using philosophy, psychology and scans of the human brain. On one hand, we can say that when we are younger, one year represents a much larger portion of our lives than when we are older. If we are 10-years-old, one year is 1/10th of our lives. If we are 80, it represents only 1/80th part. But this alone does not explain why we feel time the way we do. Why do some people feel time passes faster than others of the same age and relatively similar experience?
It is this that Wittmann seeks to explore. While his analysis is fascinating, I found one blind spot to be the lack of class analysis. While he explains that people with more variety in their lives - less routine, more novel experiences - and those who practice mindfulness are able to savor time and experience it more slowly, he does not pay much attention to the fact that there is a class element to this. It is easier for an upper-middle class manager to practice mindfulness than for the mother who is working two jobs to put food on the table for her children.
The work deals with delayed gratification, mindfulness, memory, and so much more. I found the material fascinating overall. It gave me quite a bit to think about. That said, as I started to write this review, the words and ideas came to me very quickly and now, I find myself struggling to think of what to say next. Felt time indeed.
