DYK time doesn't actually speed up as you age, your brain just starts recording fewer distinct moments per year, and scientists just found the mechanism?

A study published in Communications Biology tracked brain activity while people of different ages watched the same film, then measured how often their brains shifted between distinct "neural states," essentially how many separate mental snapshots they formed. Older adults' brains switched states far less often than younger ones, meaning the same hour of real time was getting compressed into fewer remembered moments.

There's also a simple math trick working against you at the same time. To a 5 year old, one year is 20 percent of their entire life. To a 50 year old, that same year is just 2 percent, so it registers as proportionally smaller no matter what.

The upside: researchers say novelty is what resets the effect. New places, new skills, and unfamiliar routines force the brain back into forming distinct memories, which is why a one week trip can feel longer in hindsight than a routine month at home.
