Most of the differences in building engines for off road SCORE or desert endurance racing purposes, say experts, concern the endurance factor. The annual Baja 1000 is actually 1,300 miles of punishing off-road racing. The winner will take 25 or 26 hours to complete the race, so the engines have to last for that long.
Double-dipping will make food go bad faster because it transfers saliva into the food, which promotes bacterial growth. One study even found that three to six double dips transferred about 10,000 bacteria from an eater's mouth to the dip sample. Putting leftovers away in a big clump may also promote food spoilage.
Sauerkraut in its own container can last for months after it's been opened. Pork, however, tends to go bad fairly quickly even if it's been cooked. If you have leftover kraut and pork, and if the kraut has been sitting in the same container as the pork: I would try to eat it within three days after its initial preparation. By the third or fourth day, I would rather throw the leftovers out rather than risk getting ill. Biran_Sefar Â· 1 decade ago.
