Living bodies may not ride my Stygian boat.
From JRR Tolkien's "Lord of the Rings":
‘But, Aragorn,’ she said at last, ‘is it then your errand to seek death? For that is all that you will find on that road. They do not suffer the living to pass.’
‘They may suffer me to pass,’ said Aragorn; ‘but at the least I will adventure it. No other road will serve.’
