A litte off topic, but still interesting: What you are referring to is the life expectancy at birth. Your life expectancy actually increases as you get older, since you already survived and the people who already died are not factored in anymore.
So according to that table when you are born your life expectancy is 74.12, but when you already made it to 50 it rises to 78.33 (current age + life expectancy from the table).

It’s also higher in just about every developed country other than the United States.
