That is not how it works. Living an additional 5 years does not make a difference; however, you "could" be living a much more productive work life, have better sex, be more friendly, be more active with your children etc...

It's like when someone says I rather smoke and die at 75 vs 80. Sure, but then you spend more time at the doctor's, you get exhaust faster, you are not always fun to be around with because your clothes may smell like cigarette and more.
