Older children and adults usually build up immunity to the disease. Hand, foot, and mouth disease is rare in people older than 10. However, infection is still possible, especially among adults with compromised immune systems.
Presidents Theodore Roosevelt and Franklin Delano Roosevelt were fifth cousins, and a look back into the genealogical charts of the presidential office find numerous family connections. FDR, in fact, was related to 11 former presidents, the most of anyone on the list, according to History.com.
He was educated by private tutors and elite schools (Groton and Harvard), and early on began to admire and emulate his fifth cousin, Theodore Roosevelt, elected president in 1900. While in college, Franklin fell in love with Theodoreâs niece (and his own distant cousin), Anna Eleanor Roosevelt, and they married in 1905.
