Reigning world, Olympic champion laid back in attempt to solidify place among sport's legends

China's "Super" Lin Dan remains a picture of calm ahead of his bid for a fourth consecutive world title at the Badminton World Championships, which start today in Paris.

Lin, 27, won three successive men's singles titles between 2006 and 2009, also taking the crown in 2008 when the Beijing Olympic Games were held instead of a world championship.
