time-perception

A summer at age eight felt endless. A year at forty disappears. This is not nostalgia distorting judgment — it is a measurable difference in how the brain processes and encodes time. Multiple mechanisms are involved: a mathematical relationship between age and perceived duration, a decline in the novelty that creates dense memories, slowing neural processing speed, and falling dopamine levels that alter the brain's internal clock. Each mechanism operates independently, but they all converge on the same result: subjective time accelerates across a human lifetime.

In a crash or fall, time seems to stretch. The science says it's not real-time slowdown — it's denser memory. Here's how the brain does it.
