Who'd a thunk it?
Accepted wisdom, since the publication of Krakauer's book on the life and death of Chris McCandless, has been that the manner of his death was simple enough: starvation.
This now seems to have been revised. McCandless died because some of the seeds he ate as a result of the foraging aimed to stave off starvation were poisonous. Might he otherwise have survived until help (in the form of the hunters who used that school bus as a shelter in their spring hunt, the folks who found his body) might have arrived?
