Comedy!
Narain Karthikeyan know better that he is not in 20s and not one of those Europeans who have well built physique. Jumping over the wall like every body and over estimating his capability was a blunder. Further to add to all these was his insistence to partcipate in the race after the shoulder displacement. One jerk would have brought the displacement again leading to disasterous consequences. Of course it was a freak accident. But, Sorry for the Kolles team.
