The Boston Marathon is an annual event hosted by the city of Boston, Massachusetts
on Patriot’s Day, the third Monday of April. It began in 1897 and was inspired by the success of the first modern-day marathon competition in the 1896 Summer Olympics. The Boston Marathon is the world’s oldest annual marathon and ranks as one of the world’s best-known road racing events. The first marathon started with 18 participants, and today it attracts an average of 20,000 registered participants each year. It is the most widely viewed sporting event in New England.

Carlos Ray "Chuck" Norris is a martial arts expert and actor who, after a 
stint in the U.S. Air Force, began his rise to fame in martial arts and has
since founded his own school, Chun Kuk Do. As a result of his "tough guy"
image, Norris appeared in a number of action films, such as Way of  the
Dragon (1971) in which he starred alongside Bruce Lee and was Cannon
Group movie studio’s leading star in the 1980s. He next played the starring
role in the CBS television series Walker,Texas Ranger from 1993 to 2001.

In 1909, Chicago publisher William D. Boyce (above) lost his way
in a dense London fog. A boy came to his aid and, after guiding
the man, refused a tip, explaining that as a Scout he would not
take a tip for doing a Good Turn. This gesture by an unknown
Scout inspired a meeting with Robert Baden-Powell, the British
founder of the Boy Scouts. As a result, Boyce incorporated the  
Boy Scouts of America. He also created the Lone Scouts, which
merged with the Boy Scouts of America in 1924.

MORRO BAY, Calif. (AP) — Jack LaLanne, the fitness guru who inspired television viewers to trim down and pump iron for decades before exercise became a national obsession, died Sunday. He was 96.

LaLanne died of respiratory failure due to pneumonia Sunday afternoon at his home in Morro Bay on California’s central coast, his longtime agent Rick Hersh said.

Lalanne ate healthy and exercised every day of his life up until the end, Hersh said.
