Like com'on man! Lin Dan reached the finals of the World Championships, and people are talking about his downfall. Like a silver in world championships is a dream for most badminton players, and something most badminton players, even at pro levels, never achieve. Also, Taufik Hidayat, and Peter Gade kept playing badminton for a LONG time. It was in fact getting embarrassing when they were loosing in initial rounds of the tournaments, and weren't even able to progress up to quarterfinals. Lin Dan on the other hand, still has one of the best win-loss ratio of the season, has reached a WC final, is ranked in top 5, and won the Malaysia Open. He can very well go on playing until Tokyo. The only thing he needs to work on is motivation, desire, and fitness. Learn something perhaps from Federer. His skills are still very good.
