@SirSquax Longer if you condition on them already having lived to be 76 and 80.

~55.5% chance if it were random American 76 and 80 year old males

76 year old male: (1-0.026831)*(1-0.029855)*(1-0.033151)*(1-0.036829)*(1-0.041122)*(1-0.046102)*(1-0.051683/5) = ~79.6%

80 year old male: (1-0.041122)*(1-0.046102)*(1-0.051683)*(1-0.057896)*(1-0.064863)*(1-0.072731)*(1-0.081626/5) = ~69.7%

@PatMyron They're definitely not random. They're former presidents! We try to keep those alive as long as possible.

@Quate "Take the first eight Presidents, for example – the average lifespan was 79.8 years, during a time when life expectancy at birth for men was less than 40 years old."

Rounding off and extrapolating to today's life expectancy, presidents should live to 154.
