I know you are. This is why you get some cells from when they are young and then use those to replicate from to create an immortal person. Parallel, right?

If you replace cells that can only divide for 20 years with new ones that have the same 20 years in them, you don't add any more time.You only get a lengthened life span if you can replace cells with ones that are healthy and can divide more times than the original.
Not if you save some cells from when you are at your peak. Then only replicate from those and continually preserve them. Actually, you'd only need the contents of a healthy cell. Just replicate a few of those and freeze them all. then rejuvenate from what you have in storage. Constantly replace them, of course...and be quick so it doesn't divide when you retrieve a sample to replenish your aged cells.

But that isn't something we know the ninja being capable of.They don't have good gene therapy, and their attempts to do genetic stuff tends to be very hit-and-miss in general (with Yamato being the only 'success' at all, and that seems as much chance as anything else).
I'd suspect they'd likely kill people the majority of the time if they tried this sort of thing, and of course you need to do it occasionally to keep someone young.
I don't think they have any gene therapy. It looks like their entire plan is to just replicate existing cells (senju cells). That works fine, of course. That's still better than anything we can do today, actually.
But that's more than enough. But it only requires healthy cells to do.

Also, that'd only be useful for people who they have good young cell samples of, which not many would have.
Since "immortality" of strong ninja would be a really really handy thing to have, it's very easy to put two and two together: "Hey, I can quickly replicate cells. Why don't we get small samples from ourselves when we are at our peak health and then constantly replicate new cells/growth from those to keep ourselves young and healthy for as long as we can stay alive?"
However, I have changed my original point.
My original point was: they can make themselves immortal or they are aging themselves. After reading over the medical nin stuff, they are just aging themselves by rapidly generating cellular growth. That's obvious. However, there is still another way: generate all new issue growth from a saved sample from when they were at their peak...problem solved. Immortality.
Also, I'm reading some of the old stuff, again. Man, the old stuff is just so much more awesome than what we are reading now. I just read the Neji Hinata fight. Much more exciting and awesome. Why? It feels like Kishi has gotten stagnant. Why did that fight seem more awesome than the stuff we are reading now? WHY? What is it about his old way of telling stories that I like more?
