-
and here's a photograph of one of the subjects
-
before and after the starvation phase,
-
here's an example of another subject in this study
-
who went from 145 to 117 pounds during the starvation phase.
-
Some of the other interesting photos in the book
-
are the testing that was done on cognitive and dexterity issues,
-
but as well as a lot of biological measures.
-
Then there were these anecdotes, for example,
-
of the low body temperature that gets created by starvation
-
where people just can't feel warm
-
and so these men were laying out in the sun
-
trying to get as warm as they could.
