I understand the life expectancy of US people is in the mid to high 70s, but my question is what are the odds of actually reaching that age? The reason I ask, is because a janitor at my kids' school fell and hit his head on Friday, and later died this weekend. I got to thinking about how many things can kill you, and how just a simple little accident can end it all. That led me to wonder what the actual odds are of someone actually reaching their full life expectancy. Anyone have a clue or know of any studies done on the topic? Do we have a 50%, 75% chance etc., of reaching full life expectancy?
