When you’re 5 years old, a year is 20% of your life. And when you’re 50 years old, a year is 2% of your life. This is an explanation given why time speeds up as you age. It's called Janet's law. It states you’ve experienced roughly half of your perceived by life by 20 years old. Or to put it another way: A summer holiday for a 5 year old feels as long as the 10 years from 40 to 50 years old. But Janet's law can be broken with high agency. You have agency over the speed time. You're not a passive victim. A better explanation of why time speeds up as you age is because you have fewer new experiences as an adult, so your brain deletes the memories. If you take agency over your life, do new things and create memory dividends, time slows down. If you live your life on autopilot, you may die at 80, but feel like you died at 20 years old. If you take agency over your life, you may diet at 80, but feel like you died at 200 years old.
