🪙 10 heads in a row vs 🎂 Living to 100
Share card
You're 10.2× more likely to live to 100
than to flip heads 10 times in a row
Periods differ: Living to 100 is framed as lifetime (approx. US birth cohort), while 10 heads in a row is per sequence of 10 fair flips. The multiplier is a raw ratio of the 1-in-X figures — not a normalized lifetime risk. Compare cautiously.

How we calculated this
Each figure is “1 in X.” The larger X is the rarer event. Dividing that number by the more common one gives the multiplier: you're 10.2× more likely to live to 100. When the periods differ, this is a raw ratio of those figures, not a lifetime-normalized risk.
