Query: Not so true story

Odd that Rawicz's Mongolians walk everywhere rather than ride horses, and dress in conical hats (something no one else has observed). Odd that he claims to have gone for 12 days in the Gobi without water - he must have been ready for a beer or two after that. And perhaps he had consumed more than a couple of beers when he met the yetis in the high Himalayas.It's also odd that Rawicz has refused to authenticate any of his claims and declined to produce records, photographs, witnesses, or the full identity or whereabouts of the other survivors.I think the bit on the cover, which claims that this is a "true story", may need revising.
