I have other retina permanently damaged, and suffer from double vision when looking small objects like text.
Cancer is a sensible answer.
It looks like one of the optimization edges walked by evolution is a conflict between longevity and the ability to repair and regenerate versus not getting cancer.
It’s easy to make human cell lines immortal, but that will kill you.
One route I can imagine to radical life extension is to start by editing the genome to introduce much more robust but different anti cancer adaptations. Then start turning regenerative stuff and things like telomerase back on.
It's visible in death causes - pretty much all non accident deaths are divided between cancer and heart attack.
A very interesting thing discussed in that podcast was about transgenic (or maybe all?) lab mice bred in USA. These mice are used for initial screening for nearly all drugs. And due to some error and ignorance, unbeknownst to most people using the mice, nearly all mice are predominantly on one side. (Sorry, don't remember which). They just all come from the same family.
Which means that nearly all drugs in the past few decades are skewed toward either giving people cancer or heart attacks.
This is due to mice being extra resistant to one of these and therefore not properly signaling when the drug is likely to give people heart attacks or cancer.
Sorry, don't remember which it is exactly.

Until today, it recovered completely
Is this sentence better?
Besides the blood getting everywhere and needing superglue to stop it, it grew back completely fine.
Additionally, too low angle will make the knife very suspectible to blunting and/or require constant drawing on the sharpening steel¹. Unless you have super high quality steel like Japaneese knifes or some craft smith knifes.
Butcher knifes, to be used along with a chainmail glove, are fine. Just don't test their sharpness on body parts. Or use them to shave a bit of hair, but very carefully.

(Probably for a good reason)
In a frog they were able to grow legit eyes in the gut just by artificialy inducing a certain voltage in that area. No need for any cell transplantations: the voltage really seems to be the only signal needed.
This might also be how it might be done in the future in humans: block scar tissue then induce voltage with the signature of the organ you wish to regrow.

Dude's brother had him throw his product on the finger as it did so, definitely an astute marketing trick. https://www.theguardian.com/science/2008/may/01/finger.claim
To be fair, the person being skeptical is just a surgeon, this is not a peer-reviewed study or anything actually scientific.
Your NPR link even shows that scientists realize there are still unknowns:
> "We think that nail stem cells may a have a special function to induce the whole regeneration process, including nerve attraction and growth of the bone," Ito say.
A cursory search seems to say that typical regrowth of a nail takes 4-6 months, but Spievak claimed his only took 4 weeks.
Can we say definitively that his "pixie dust" had nothing to do with it? I don't think so. Can we say it did have something to do with it? Also unknown... but the answer right now IMO certainly isn't a scientific "no."
I think this is what all healers used. They were all way ahead of their time and clearly misunderstood.
For His own mysterious reasons, He simply doesn’t go in for that stuff, however much intercessionary prayer ends up in His inbox.
in Folio 43a of Tractate Sanhedrin of the Babylonian Talmud as follows:
‘It is taught: On the eve of Passover they hung Yeshu and the crier went forth for forty days beforehand declaring that "[Yeshu] is going to be stoned for practicing witchcraft, for enticing and leading Israel astray.”’
The relevant portions of the Bible record that the Jews of the Sanhedrin acknowledged the signs and miracles but said it was by the power of Satan that he did these things.
