You're arguing that those who survived this long will survive more than 10 years. I mean, yes, but

1) food in this economy is still delicious so heart disease is still the cause of 50% of deaths, and

2) humans only have one copy of p53 from each parent, so everyone dies of cancer if Heart disease or <random> doesn't get them first.

Given 1 and 2, the boomers are on their way out. My mom (born 1953) might make it another 20 years, but my dad (born 1945) is living on borrowed time (20 pk-yr history and cancer).

It is how actuarial tables work. Baby boomers in 2032 will be between 68 and 86 years old, and mortality increases rapidly up to and including those years.
