A piece of presidential trivia

I was perusing a web site that tells somewhat odd details about each president, next to a photo of a plastic minaturette of each one.

Just by happenstance I noticed that 3 of the first 5 presidents died on the 4th of July. Weird.

JOHN ADAMS, d. July 4, 1826 at 90.
JEFFERSON, d. July 4, 1826 (Charlottesville, VA) at 83.
MONROE, d. July 4, 1831 (New York, NY) at 73.
