I think all of those are interesting questions in their own right.

And we as humans have been wondering about aging and death all of our existence.

So now that biology has made advances and actually has some light to shed on these problems, I think it's an interesting thing.

I think bringing somebody back who's already died

is currently in the realm of science fiction it's i know there are companies that freeze bodies some of them even just freeze brains but there's absolutely no evidence that any of those bodies or brains can be resuscitated even in principle nobody has shown that even for a tiny

Well, even for an animal like a mouse, they haven't been able to freeze a mouse and bring a mouse back.

They have done it for very small animals like worms, tiny worms, and they do it for cells all the time.

We freeze cells all the time.

That's been used even in animal husbandry.

But freezing even a small animal has not yet been done.

It's interesting because You know, everybody thinks they know what DNA is. They've all heard of it. Even if they don't actually know what DNA does, they know it has something vaguely to do with our genes. But if you ask them what a ribosome is, most people have never heard of it. Never heard of it.

Never heard of it.

And the thing about the ribosome is without the ribosome, DNA would almost have no meaning because DNA encodes genetic information. but it's really the ribosome that reads that genetic information to produce that whole orchestra of proteins that makes a cell actually be able to live, carry out all the reactions, but also build all of the structures in the cell.

All of those structures are either made of proteins or built by proteins. So I like to say that almost everything in the cell was either made by the ribosome or was made by enzymes that were made by the ribosome. So you can think of it as the sort of mother or grandmother of all things in the cell. And it's also older than DNA. It goes back to an RNA world.
