I was trying to think of a way to reverse aging And I though

I was trying to think of a way to reverse aging. And I thought about all errors that accumulate in your DNA over the years and I wandered what would happen if you donated blood at an early age and then received transfusions of your own blood when you were older?

I assume there are many things I am over looking like immunity that you acquire when you\'re older and the fact that when you get a blood transfusion from someone else it obviously doesn\'t replace your DNA.

But maybe a bone marrow transplant, or some way of infusing DNA without errors or repairing your DNA in someway.

Also I figure there is something I am not considering when it comes to factors such as different localities in the body, I know in Chimerism you can have the body pumping out different sets of genes in different parts of the body.

Solution

Ageing is complicated. We know that the underlying reason that the body ages is that as we live our lives, our cells accumulate a whole host of small faults, damage affects the DNA, proteins, membranes that make up the cells. So basically, the ageing process is driven by things going wrong, cells become damaged, and that also affects the stem cells of the body. It used to be thought that stem cells could keep going more or less indefinitely, but actually, we know that stem cells that underpin many parts of the body do themselves experience some form of intrinsic ageing.

So, in theory, one might think that a good way to combat some of the effects of ageing would be to replace the cells within the body that had been damaged by this accumulation of faults with cells that are somehow less damaged. And the idea that you could use your own banked cells from earlier in your life is an interesting one. There are problems with that though, ageing affect all the cells and tissues of the body, so simply rejuvenating one particular population of cells maybe do it for that group of cells, but it
