In both cases the actual length of time without food was fuzzy because there was some food, i am not demeaning the ordeal, just saying that the media loves to leave out info to catch your attention.
The Penticton woman's ordeal did not include temperatures of -30 and she had water. Eating snow significantly decreases your body core temperature. When i searched i found that the Swede did indeed have warm clothing and a sleeping bag, along with there being evidence of much more food that originally stated.
