Frequently Asked Questions
Why is this useful?
Inspired by Tim Urban's "The Tail End" essay. Reframing time-left in concrete units (weeks, dinners, summers) makes priorities clearer than abstract years.
What life expectancy should I use?
Country average for your sex + age cohort, adjusted for: smoking (-7y), heavy drinking (-5y), obesity (-5y), regular exercise (+3y), strong relationships (+5y), wealth (+5y in many countries).
Is this morbid?
No. Stoics, Buddhists, and most thinkers throughout history call it "memento mori" — remembering mortality clarifies what matters. Mark Twain, Marcus Aurelius, Steve Jobs all advocated it.
