Are We Running On Martian Time?
It is really very curious. In the absence of all external time cues, the human body slowly shifts its internal clock from earth time (24-hour days) to Martian time (24.9-hour days). Could we all have been Martians in the deep, distant past? This thought was triggered by the recent surmises that earth life might have originated on Mars and been brought here by an immigrant meteorite.
