Question 1

What is Janet's Law?

Accepted Answer

It's a psychological phenomenon proposed by French philosopher Paul Janet regarding the perceived passage of time. It states that our perception of time is inversely proportional to our age, making a year feel shorter as we grow older. This app quantifies your perceived remaining life based on this law.

Question 2

What is Perceived Lifetime?

Accepted Answer

It's the length of remaining life you actually 'feel', calculated using Janet's Law. Rather than the number of years on a calendar, it visualizes how much time you feel you have left. A surprising result is that many people feel they've already spent half of their life by around age 20.
