It's mad enough that there was a world record for this in the first place but the fact that it was broken by a teenager just adds to the mind bogglement.
16-year-old Bosnian taekwondo champion, Kerim Ahmetspahic, smashed 111 concrete blocks with nothing other than his head (and gravity) in front of a cheering crowd in the Bosnian city of Visoko over the weekend, setting a new world record for the stunt.
The previous record, in case you were curious, was 65 blocks but that took Oliver Gimsehl a minute to do.
Ahmetspahic's 111 blocks? Just 38 seconds.
