“You should know that 9 out of 10 people who undergo this surgery will die. But don’t worry, the last 9 people who took this surgery all died, so you’re in the clear!”
Technically 1 out of 1 people who undergo that procedure die, eventually. Same is true for people who elect not to have the procedure done, eventually.
That’s not confirmed. Only about 93% of people who ever lived died so far.
Death rate is also strongly correlated with when you were born. We’ve gotten much better at not being dead in the last 100 years. For people born in 1924 the death rate is nearly 100%, but for people born in 2024 it has dropped close to zero!
