I'm not sure that calculation makes sense. If someone has already lived to 77 he probably has a much higher chance of living to 78 than the average person. And if someone has lived past 78 does that mean he's lost negative years of life?

Yep, 78 is life expectancy at birth. Your life expectancy goes up every day you are alive.

Well... every day bar one.
