When people talks about life expectancy 99.99% of the time they mean life expectancy at birth, at every year the life expectancy change. Using this life table someone with 61 years, have a life expectancy of 19.7 years, that means he's expected to live until he's 80.

Yep, and that was true even going all the way back through history. People weren't routinely dying in their 30s or whatever before modern medicine; it's just that a lot more of them were dying in infancy/early childhood and that brought down the average.

I would say it’s appropriate to loop cancer deaths into the “old age” bucket – DNA getting old and making mistakes replicating seems relevant.
