Life expectancy in many countries is mid 80s.

That doesn't seem to be true, the global expectancy is 73 and only a dozen of the wealthiest countries are mid 80s. I wouldn't be worried about dying at 70, but maybe I'm built of tougher stuff.

You say my claim is not true then proceed to acknowledge it is true. To be clear about the fact: about 1/4 of all countries have a life expectancy >80, and as you said, more than a dozen in mid-80s.
