Mark couldn't care less about anything anymore, not since he swapped bodies with Carol. He figured he had nothing to lose. He disassociated himself from the consequences of his actions; feeling Carol's body would be suffering any ill effects. He drank all the time, even when driving. He rode his motorcycle without a helmet. Nothing seemed to matter to him anymore... He thought to himself that maybe if he died, it would jolt his consciousness back to his own body. Or maybe he missed his own body so much that it just didn't matter if he died.
