HOW OLD WERE THESE WRITERS WHEN THEY DIED!

I was interested in finding out if there was any particular age at which writers tend to die.  I know--morbid focus!  In order to get a sense of this I randomly picked out a bunch of literary figures and located the age at which they died.  As you can see below, there doesn't appear to be any particular trend in regard to age.  It was interesting to do, however. See below to get my results.  If you would like to, don't hesitate to add more names to the list!
