The Danes are well-known as late bloomers. Look at Eriksen/Hansen....they started to make noises only in the past 4 years. First, they won the All-England in 2004, squeezed through to the Semi-Final of the Olympics 2004, before winning the All-England again in 2006.
The number of titles Eriksen/Hansen won in the past 4 years way surpass their entire performance when they were younger.
The same goes their "new" pair: Simon Mollyhus/Anders Kristiansen. Mollyhus is 24 yo while Kristiansen is already 28.
You gotta have a true professional attitude to play top level badminton in your 30s.
