Move to a country with socialised healthcare and reasonable unemployment systems.
Develop a mental illness, you're 36 so you probably have a couple already.
Apply for disability and reduce your workload to 20 hours a week.
Have your parents die so you can have a chance at owning a house so you have somewhere to die other than hospice.
Kids are a double edged sword, kill you now, look after you later. Might be better financially to not bother, as you'll have to go back to full time work just for a chance to ensure they don't grow up neglected, and if they do there goes your retirement.
Also Kids are not a double edge sword. You are not supposed to have kids, so they take care of you when you are old. That's just a recipe for them growing up neglected.
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).
