A theoretical study suggested the maximum human lifespan to be around 125 years using a modified stretched exponential function for human survival curves. In another study, researchers claimed that there exists a maximum lifespan for humans, and that the human maximal lifespan has been declining since the 1990s.
The "3-3-3 Rule" for habits is a guideline suggesting it takes 3 days to start, 3 weeks to build consistency, and 3 months (about 90 days) to solidify a new behavior into a permanent habit or lifestyle change, acting as a psychological tool to break down overwhelming goals into manageable phases. It helps you push through initial resistance (days), establish a routine (weeks), and integrate it fully (months), though real change happens through consistent identity-based action, not just the numbers.
