> I honestly thought it was something every older person needed to have on their radar as a possibility. I mean, to me 1/500 chance per year sounds like it's right along the lines of "every older person needed to have on their radar as a possibility". The average person lives to 80, so 1/500/yr means a 16% chance per person of having to undergo that operation. That definitely seems high enough to be "every person should have it on their radar as something that might happen to them".
