Robert Edward Machado (better known simply as Rob Machado) (b. October 16, 1973 Sydney, Australia) is an American professional surfer from Cardiff-by-the-Sea, a community in Encinitas (San Diego County), California.

Machado attended San Dieguito High School, and is known for his casual, "laid-back" style both in and out of the water. Though he rides a modern tri-fin shortboard, he could still be considered a "soul-surfer" because of his smooth cut-back style that has earned him the nickname "Mr. Smoothy". He is one of the best-known goofy-foot surfers in the world today.

Rob has won many of pro surfing's most prestigious contests, including Hawaii's Pipeline Masters (Triple Crown of Surfing), and the U.S. Open of Surfing, the largest surfing event held on the U.S. mainland. His 2006 win in that competition was only his latest at Huntington Beach, and it came on the heels of his victory at the 2006 Monster Energy Pro (also held at Pipeline) on Oahu's North Shore. Also, Rob was on the "West" team that won the 2006 Summer X Games surfing competition, called "The Game", held each year in Mexico.

Waldo Vieira (born 12 April 1932) is a Brazilian dentist and physician who first proposed the theories of projectiology and conscientiology, two closely related nascent sciences which posit that human consciousness is a non-physical phenomenon. That is, Vieira argues that consciousness has an existence independent from the body, basing his claims on various accounts of out-of-body experiences and other psychical phenomena. He has written over twenty books on vital energy, parapsychical and personal development, and out-of-body experiences, including accounts of personal experiences.

Waldo Vieira was born on 12 April 1932, in Monte Carmelo, Minas Gerais, Brazil. He is a physician and a dentist. He also holds a post-graduate degree in plastic surgery, earned in Tokyo, Japan. Vieira claims to have begun experiencing out-of-body experiences at the age of 9, and for the past 40 years he has explored the idea of consciousness as something other than the body.

Having written four 1000+ page treatises, a series of books and hundreds of articles, Vieira is among the most prolific authors on the subject. However, his work has been described as reflecting "the author's strong personal beliefs", which cause "many [of his] statements [to] seem strident, even dogmatic." Still, it has also been argued that his work has some value "as a phenomenological treatise with applications to the consensual world that necessitate verification or refutation by other researchers."

David Villa Sánchez (Spanish pronunciation: [daˈβið ˈβiʎa]; born 3 December 1981), nicknamed El Guaje (Asturian: The Kid), is a Spanish footballer who currently plays as a striker for FC Barcelona and the Spanish national football team. He can also operate as a winger.

Despite sustaining a serious injury as a child, he started his professional career with Sporting de Gijón. He moved to Real Zaragoza after two seasons, where he made his La Liga début, winning his first senior honours—the Copa del Rey and Supercopa de España. He joined Valencia CF in 2005 for a transfer fee of €12 million and was part of the Valencia team that won the Copa del Rey in the 2007–08 season. In 2010 he moved to FC Barcelona for €40 million where he won his first La Liga and UEFA Champions League titles.

Villa made his international début in 2005. He has since participated in three major tournaments, becoming an integral member of the Spain teams that won Euro 2008 and the 2010 World Cup. He scored three goals at the 2006 World Cup, was the top scorer at Euro 2008 and earned the Silver Boot at the 2010 World Cup. He is the first Spanish player to ever reach 50 international goals and is Spain's all-time top goalscorer, having has also scored more World Cup goals than any other player in Spain's history in the process. The goals-to-games ratio he has achieved for the national team has not been matched by any player since Alfredo Di Stéfano.

Robert Alexis Machado [ma-CHAH-do] (born June 3, 1973 in Puerto Cabello, Carabobo State, Venezuela) is a former catcher in Major League Baseball who played most recently with the Texas Rangers organization. Previously, Machado played for the Chicago White Sox (1996-1998), Montreal Expos (1999), Seattle Mariners (2000), Chicago Cubs (2001-2002), Milwaukee Brewers (2002), and Baltimore Orioles (2003-2004). He batted and threw right-handed.

Machado was a solid defensive catcher with a strong arm, but his little offensive value limited his effectiveness as an everyday player. His most productive season came in 2001 with the Cubs, when he posted a .997 of fielding percentage and threw out 13 of 39 baserunners who attempted to steal off him. He also had eight multi-hit games, including three over a six-game span, when he went 9-for-23 with three doubles and a home run.

In a nine-year career, Machado was a .230 hitter with 11 home runs and 61 RBI in 230 games.

Machado received a 15-game suspension for violating Major League Baseball's minor-league drug treatment and prevention program.
