Recently we had friends over for dinner and I was describing someone no one else in the room knew. I said "He's kind of middle-aged...you know, around my age." One of my friends laughed and said that I wasn't middle-aged. Which was reassuring, but was he right? If you look at average life expectancy I'm over halfway there. So I searched the 'net and found this British article that helped me figure it out for sure.
