Man survives, trapped in a snow-bound car, for 2 months.

This happened in Sweden, where the temperature was as low as -22°.

The man, who was too weak to utter more than a few words, said he had been inside since 19 December. He may have survived by drinking melted snow.

Police say they have no reason to doubt his story.

Hmmm. Isn't his survival, under those conditions, a reason?

One doctor told the newspaper that the man might have survived so long by going into a kind of hibernation.

Hibernation! Can human beings hibernate? That's a good question to ask Google. I came up with this:

A Practice closely akin to hibernation is said to be general among Russian peasants in the Pskov Government, where food is scanty to a degree almost equivalent to chronic famine. Not having provisions enough to carry them through the whole year, they adopt the economical expedient of spending one half of it in sleep. This custom has existed among them from time immemorial.

At the first fall of snow the whole family gathers round the stove, lies down, ceases to wrestle with the problems of human existence, and quietly goes to sleep. Once a day every one wakes up to eat a piece of hard bread, of which an amount sufficient to last six months has providently been baked in the previous autumn. When the bread has been washed down with a draught of water, everyone goes to sleep again. The members of the family take it in turn to watch and keep the fire alight.

After six months of this reposeful existence the family wakes up, shakes itself, goes out to see if the grass is growing, and by-and-by sets to work at summer tasks. The country remains comparatively lively till the following winter, when again all signs of life disappear and all is silent, except we presume for the snores of the sleepers.

This winter sleep is called 'lotska'. These simple folk evidently come within '0 fortunatos nimium sua si bona norint!'

In addition to the economic advantages of hibernation, the mere thought of a sleep which knits up the ravelled sleeve of care for half a year on end is calculated to fill our harassed souls with envy. We, doomed to dwell here where men sit and hear each other groan, can scarce imagine what it must be for six whole months out of the twelve to be in the state of Nirvana longed for by Eastern sages, free from the stress of life, from the need to labour, from the multitudinous burdens, anxieties, and vexations of existence.

Much more on human hibernation if you go to that link or Google as I did, but I'll stop there, because it's so cool. And cold.
