Talk about the topic

Parts A and B

Really? Why not?

Well, I was really disappointed that she finished by talking about the natural approach.

Huh?

You know, how if we use a natural approach to slowdown aging, we don’t have to use any high-tech solutions.

Okay.

Well, taking a natural approach, it seems like common sense. I mean everybody knows that.

I’m not so sure about that. I don’t think it’s common knowledge at all. I mean, that part about over eating having a connection to aging was news to me. And I consider myself pretty well informed.

Actually, I think people already know what they should do, but like me, they just don’t.

Why is that?

Well, in my case I don’t have the time or the money to eat a super healthy diet. And I’m definitely not gonna cut it back by 30%. I’d be hungry all the time.

So, what then? I mean, if you don’t live a healthy lifestyle, your body will just break down faster and you’ll have to get a new heart some day.

Sorry to change the subject, but can I clarify something from earlier in the lecture?

Ohum.

So, has the Hayflick Limit theory been disproved? I’m talking about the interpretation that your lifespan is predestined.

By predestined, you mean…

Already decided. Like the idea that at the time you’re born, how long you’re going to live is predestined.

I didn’t take it that way. I think new research shows that you can slow down the rate of cell division and therefore what did she say about the clock?

Slow the hands of the clock.

Right, and live longer.

Well, I guess that’s a good thing.

Yeah.
