This is like the old “Presidents elected in years ending in zero never live to complete their last term in office”. Back in the 1980s, everyone knew that Reagan would die before 1988 because of the “curse” that killed Lincoln, Kennedy, McKinley, and FDR. Of course, 8 years of Reagan and 8 years of GWB put that “curse” to bed forever.
Actually, that “curse” ignored the fact that Jefferson and Monroe both lived past their terms in office. Jefferson was elected in 1800, Monroe in 1820, both years ending in zero. Apparently this “curse” only started because of a long inaugaral address in cold weather leading to a case of pneumonia.
