Who, What, Why: How long can someone survive without food?

A Swedish man, found in a car buried under snow, says he survived for two months without food by eating handfuls of snow. But how long can people go without food?

Peter Skyllberg's survival are still being investigated. However, photographs taken of the inside of the car show empty food and drink wrappers, which could mean the 44 year old had some sustenance.
The car was found on Friday at the end of a forest track more than 0.6 miles from a main road in northern Sweden. Police say the temperature in the area had recently dropped to -22F.

This man was said to have been stuck in this car for 2 months; surviving on nothing but snow and possibly a small supply of food. Being stuck in a car for that long would be horrible. Especially when it is that could. They say it’s possible for the human body to survive 2 month without eating, but that’s a long time. He was lucky to survive.
