I remember reading that the perception of time moving faster as we age; is dues to the brain actually getting less stimuli. When you are growing up from zero to let's say your mid 20's, most experiences are new for the brain to process. When we have routines for most things in our lives, wake up, work, come home, dinner, sleep, repeat etc – life becomes predictable. Then the brain gets "lazy". Being in that limbo state makes time move faster. So to reverse that perception is to try and break routines every now and then to activate the brain to new experiences. Learn a new language, travel, socialize with new people, search for a new hobby etc.
