Strange facts on researching presidents

While working on an article for work, I stumbled across the following. Such is research in the days of the Internet:

• Wyclef Jean is considering a run for the presidency in Haiti.
• Presidents age two years for every one year while in office, according to the Cleveland Clinic.
• One in six presidents die in office.
• From the 1940s to the 1960s, Ivy-league schools such as Yale, Vassar, and Princeton took nude photos of every freshman passing through their doors, including many dignitaries and presidents.
