Step 1 : Introduction to the question "Which U.S. president liked to skinny-dip in the Potomac River at 5 a.m.?"
...The sixth president of the U.S. had a little-known routine: he took a daily nude swim in the Potomac River every morning at 5 a.m. John Quincy Adams claimed this was his way of coping with the tremendous stress generated by serving as president of the United States. Thanks to his skinny-dipping habits, a woman was able to interview a sitting president. When Anne Royall discovered the swimming president, she hid his clothing until he agreed to allow her to interview him. Source: Reference.com
