If freezing food makes it last longer, do we live longer if we keep cold?

Your metabolism slows down at first, but if you stay in the cold, it quickens to keep you warm and to keep you alive and not in hypothermia. Slowing your metabloism doesn't make you stay younger though, makes you fat... To stay younger your cells would have to freeze and you'd be just a young looking corpse afterwards!

no because cold blooded animals are dependant of the  environment temperature \nif the temperature outside drops to 0 C you would die

Hi-\n\nAssuming that the meat was frozen while still fresh, it is "safe" indeffinitely. The problem is that over time, the moisture in the meat sublimates, or leeches out of the meat to form big ice crystals on the surface of the meat.\n\nOften times, this is called Freezer Burn and can be seen as a light area or spot on the meat. When you cook this meat, it won't make you sick, but it will be pretty nasty tasting in those spots that suffered worst.

"Their intention is to try to make them last longer prior to use. I think everybody has had the experience of putting a bunch of batteries in a flashlight and then putting it in the trunk of their car, and they go back when they need the flashlight and it doesn’t work. Because just on standing, batteries actually deplete themselves. So the idea is that there’s a certain amount of chemical inside—it’s a chemical reaction that’s taking place in the battery—and the chemicals basically get used up. They basically just run out of active material.\n\nMost chemical reactions are affected by temperature, and the lower the temperature the slower the chemical reaction. So what people are trying to do is slow down the self-depletion mechanisms of the batteries by keeping them cold.\n\nIn general, it does extend the battery’s life. Whether there’s a significant difference that would be measurable to the consumer between room temperature and a refrigerator.... To be honest, I don’t know. But in general it does work—that if batteries are kept cooler while they’re not in use it will extend their shelf life.\n\nSo then what about the freezer? Is it even better?\n\nI think one would have to be careful about that. Because it’s the freezer, and the freezer is quite cold. Depending upon the type of batteries, you can actually freeze some of the internal components, and that would not be good. So probably the refrigerator is a safe bet and it will improve things a little bit.\n\nWhat if there are batteries that you’ve been using but will not use again for a while. Would placing them in the fridge in the meantime help at all?\n\nYeah, if you plan on storing them for a long time, it probably would. I think typically people put them in the refrigerator before use. Certainly people should not try to use the battery or activate the battery while it’s cold. It may not work very well. But if they let it warm up before they use it, it should help. \n\nWhat about batteries that are starting to run low?\n\n\nNo, that won’t help. When they start to run low they’re basically used up."

By removing the air you reduce the likelihood of aerobic bacteria, preserving food longer and preventing freezer burn in frozen foods.

Not very long. In most circumstance 5-7 minutes. However, in some cases, let's say, when someone falls into a half frozen pond or something, the cold is suppose to slow down their body system enough that there have been a few cases where people have been pulled out of FREEZING water 20 minutes later and they lived. Some may have had brain damage but they lived. I hope this helps!

there are many strategies used by animals even tiny ones to survive the winter-having thick fur or an underlayer of downy feathers prevents heat loss which is the biggest problem we have in surviving the cold (you don't get frost bite on your head). bulking up in the fall ensures fat reserves to keep the body warm (most of the food eaten by mammals is  exclusiely to generate our own heat.) Also finding shelter from really cold and windy nights by grouping together for body warmth.\nSome animals like small rodents live beneath the snow where the temperature hovers around the freezing point even though it might be 20 below freezing (the subnivean zone), etc.  the biggest factor is insulation with incredibly thick fur.

bacteria begin to grow when food is defrosted or left in the fridge for any amount of time.  defrosting food lets bacteria "come back to life" which is why you should cook it in order to let hte heat kill off the bacteria.  freezing it again just allows more bacteria to grow.

Let us not forget irradiation. exposure to cesium kills all microbes in the food after it is hermetically sealed it will last indefinately at room temperature. I am not pro or con on this, just thought I would mention it.

When purchased from a grocery store, frozen vegetables are as nutritious and sometimes more nutritious than fresh fruits and veggies.  The reason is that fresh fruits have been sitting for several days in transit before they reach the store and then usually sit for a few days in your house, that whole time, they are losing nutritional value.  \n\nFrozen veggies are usually packed frozen shortly after being picked and therefore maintain their nutritional value.  Studies have shown this, check out the link below.  \n\nCanned vegetables can have similar nutritional value preservation, but some compounds like vitamin C break down during the heating process in canning.  \n\nFresh fruits have historically been viewed as being most nutritious, and it is true if you grow it yourself, pick and eat.  But if you're heading to a grocery store, head for the frozen foods for nutrition.

only if its frozen... personally I found this question tough to chew...lol...

It is true, the value of the water is less than the harm done by utilizing body heat to melt it to a usable liquid. You need both heat and water to survive, but you will die quicker of exposure than thirst. Where there is snow there is almost always liquid water, water will pool in low lying areas, and the snow above it acts as an insulating blanket keeping it from freezing. Hydrating yourself will help your body function better, and keep you warmer, just don't hydrate at the expense of lowering your body temperature.\nSurvival is often times a simple cost/benefit analysis, making well thought out decisions combined with a bit of luck can save your life.

yeah, its preserved fruit. Some are lost in heating up and over time. But making your own jam and eating over the winter is much better than buying stuff in the supermarkets.

Yes. It is generally the water-base fruits and veggies, like celery, cucumbers, and watermelon. Also, the colder they are when you eat them, the more calories your body expends while digesting.

Buy a small inexpensive freezer,dry ice,or power converter,store your frozen food in freezer and off you go.Hint dry ice will keep food frozen for about a day in a half.I used to sell meat door to door,that's how I know.Now I work offshore and we get our groceries from a boat packed with frozen food and dry ice.Sometimes we don't see the boat for 2 days and the food is still frozen when we get it.

Yes, theoretically.\n\nIF: \na) The temperature of the fridge is constant\nb) It is never opened\nc) There is a substantial difference in temperature in the beginning\n\nWhy? The temperature of the can of pop exponentially approaches that of the fridge. It will - asymptotically - reach the temperature of the fridge very soon (day 2?). However, it will get colder all the time thereafter. Not necessarily measurably so.\n\nThis is akin to the question whether a harddisk gains weight if you put data on it.
