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. (That's the situation anti-vaxxers are trying to go back to, BTW.)

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.
