An academic has called for Shakespeare's remains to be exhumed so that more can be learned about his life. Francis Thackeray, from the University of the Witwatersrand, said he was "very interested in the possibility" of examining Shakespeare's grave."Given the extraordinary success of the study of the skeleton of Richard III, we recognise the potential of undertaking forensic analyses of the Bard," he said.Thackeray believes analysis of his bones could reveal new information about how the playwright lived, what he ate and drank, and whether rumours that he smoked cannabis are to be believed.However, he acknowledged that the epitaph on Shakespeare's grave might be a stumbling block.The inscription on his tomb in Stratford-upon-Avon reads: "Good frend for Jesus sake forebeare/ To digg the dust encloased heare/ Bleste be the man that spares thes stones/ And curst be he that moves my bones."..
