Why it's higher than 79
The 79.0 years you hear about is the US average at birth in 2024. By 77, you've already passed the ages where some people born the same year died, so the average age you reach is higher: 88.9 for women and 87.4 for men.
What moves your own number
This is the average for everyone in the US aged 77, smokers and marathon runners alike. In a study of 123,219 US health professionals, people with five healthy habits at 50 could expect 12 to 14 more years than people with none (Li 2018). See your own estimate from the same study, or take the floor test.
