This guy should read
Castaway , by Lucy Irvine. Or at least watch
the movie. The "hero" took a lot more stuff to his little island, including a "wife," and still had a really rough go of it...
That book is a favorite of mine. She also wrote Rrunaway (before) and Faraway (after), two very interesting reads.
