>Fun fact: while the IFR of the seasonal flu is around 0.1%, there's around a 2.5% chance you will die from it.

That's an incorrect statement unless the age distribution of people on this forum exactly matches the age distribution of the US population, which it doesn't. The overwhelming majority of flu deaths are concentrated in the elderly; someone under sixty is orders of magnitude less likely to die than someone older than eighty.

I don't think this has to be incorrect. Or that your "unless the age distribution...." needs to be true either.

Everyone eventually dies. When that happens, as things currently stand, it will be a 2.5% chance the cause will be the flu.

You might die young or old. Across those possibilities, it is 2.5%

That can be consistent with the idea that if you were to die next year, it probably (i.e., much less than 2.5%) won't be the flu because you are a young person.
