      The cells in are body are constantly being renewed. So my question is are we constantly dying and being reborn? Or is my defenition wrong change doesn’t equate to death? Is Change part of the defenition of human life?

      Sorry if this kinda philosophical I wanted a biological answer. Can you also try to keep your answer simple i’m not the smartest person thanks.

      Only some cells get replaced. Most of your nervous system, muscle system, and some of your skeletal cells are the cells you were born with.

      I’m still a little confused are you considered dying and being reborn or are you just considered changed but still alive and have never died?

      They don’t become dead but are continuously replaced. For Example: when your hand burns or you get a cut, the cells are replaced by the old/damaged ones.

      IMO, changing cell doesnt equate death.
      IF you want to, you can refer to any scientific definition of death conjured by physician or something. I believe it involve more than justskin changing.
      Well the cells being changed were dead, and they got degraded or anything, but as individual, we are not dead (and then reborn).

      Hope it helps

      Does everybody agree that changing cells doesn’t equal death. I am curious to hear other peoples answers. Agree or disagree. Also I would prefer no religous or spirtual peoples answer

      My opinion: Being alive means to keep the organization of our body on some level. The loss of organisation means we change in not-alive particles by the process of decompositation. And since changing the cells (useless, damaged) is also helping to keep the organization, it is not dieing. It’s a way how to keep the body working – alive.

      Survival of the fittest those cells which are fit to live survive function as a part of body are live those which fail to carry out their function to the organ those are dead… Example is your own skin dead skin comes out and new layer replaces that place so this is all what about survial of the fittest…. All depends on your immunity system and the function it carries out…. T cells B cells etc end of thinking capacity….:D

      Why would that matter in the slightest? Do you want to know if the cells go to an afterlife when they renew? Personally I think the entire question is silly.

      Ask yourself this: when your cells renew does your heart stop beating in order for the cells to go through their cycle? No. Last time I checked the definition of death is all organs ceasing to function. The cellular cycle is a healthy part of life AND the individual organs that make up the body.

      Many cells have their own life cycle just as you and I do. That does not mean that the "social organism" we are members of dies. It lives on in the same way we do.

      As it has been said here, some cells live as long as we live. Others die and are metabolized to finally end up excreted from the liver or kidneys. Those many cells that are sloughed off from our skin each day certainly die.

      It is of interest that there is an atrial fibrulation drug that cannot be excreted either by the liver or from the kidneys. It accumulates, and its toxicity regulates the heart beat, but it causes a wide assorment of ill effects if taken in more than minimal doses. The only way it is excreted is in the cells that are replaced in and outside (the skin) of the body.

      I have another question does the ship of theseus conclusion agree with the conclusion that with the " definition of death is all organs ceasing to function."

      Also does it in anyway refute the definition of " death is all organs ceasing to function."

      i think that the Old, worn out cells are constantly being replaced. How well this process works (or doesn’t) is partly responsible for the outward signs we know as aging. Think of the resources needed to continually monitor the workings of trillions of cells. Your immune system is always on the lookout – not only for invading microorganisms, but also for cells that have not replicated correctly and could cause dysfunction of some kind. At least this is true if you provide the nutrients necessary for your immune system to function correctly. Even your bones are constantly being broken down and rebuilt, a process called remodeling. Your body requires resources to carry out all of this activity. How well you fuel this renewal process determines how you feel.

      If you are eating food full of calories but devoid of nutrients, your body must expend energy to process it but gets nothing in return – a net loss of energy, vitality and overall health. Think of a house that is continually being remodeled. What happens if the only building materials available are poor quality – or worse, not even correct for the job but the carpenter must make do. After some period of time, structural integrity is compromised. For example, magnesium is just one of several minerals necessary for our bodies to function. Estimates say that 50 to 80 percent of us do not get enough of this critical nutrient, which is used in 300 different functions.
