Stroke killed singer Isaac Hayes :

Soul legend Isaac Hayes, who died aged 65 on Sunday, was killed by a stroke, US authorities have said.
The musician's doctor listed it on his death certificate, while there has been no post mortem, said Memphis sheriff's spokesman Steve Shular.
Mr Shular added that Dr David Kraus was treating Hayes, who suffered a stroke in 2006, for high blood pressure.
The Oscar-winner was found at home by members of his family lying next to a treadmill which was still switched on.
