Some good old fashioned brain-in-a-jar level science fiction this week! Originally published in If Worlds of Science Fiction April 1954 by Gene L. Henderson. When does life begin? A well-known book says ‘forty’. A well-known radio program says ‘eighty’. Some folks say it’s mental, others say it’s physical. But take the strange case of Mel Carlson who gave a lot of thought to the matter.
