What advice would you give to someone who's, I don't know, in their 40s, 50s, 60s, 70s, 80s?

Like how, what should we do to be the best stewards of our brains?

I'll tell you, it's so easy.

It's to seek novelty, it's to seek challenge.

So the key is for most people as they get older, they, you know, whatever, their lives shrink,

they watch Jerry Springer, they do whatever they do.

But the key is challenging stuff.

So there's this study that's been going on for decades.

You may know about this called the Religious Orders Study, where a whole bunch of nuns in convents volunteered to give their brains upon their death.

So what happened is the researchers started examining these histological samples

and realized that some fraction of these nuns had Alzheimer's disease

and their brains were physically getting chewed up with the Alzheimer's and yet nobody knew it when they were alive.

They just weren't showing the cognitive deficits.

Okay, so they do a big understanding that, What was going on was they lived in the convents till the day they died.

They had social interaction.

They had chores and responsibilities.

They played games, they had conversations, they were doing all kinds of stuff.

And as a result, even though their brain was physically degenerating with the ravages of the disease, they were building new bridges,

new roadways all the time.

And as a result, they were able to essentially fight back against the degeneration of the tissue.

This is the important thing is to always seek challenges.

Go ahead.

I was going to say, is it challenges that themselves vary?

So if someone finds doing a crossword challenging, but they do it every day and keep doing it, is that good or is that actually,

or playing bridge every week or something like that, or is it actually much better to mix that up

and actually know I'm going to travel to a new place and whatever.

As soon as you get good at the crossword puzzles, you got to drop that and do something that's hard.

The key is to be between the levels of frustrating but achievable.

And that's where you always want to keep yourself in life.

And as long as you're there, as long as you're there, you're doing the best thing you can do for your way.

I mean, this is, I'm not- You're between frustrating and achievable.

You're always frustrated and never achieving.

That's to say.

Yeah, it's funny because there's so much that we know, you know, so much stuff pouring out in neuroscience labs, but this is still the key,

the single piece of advice really that we have for putting off dementia.

Palabras largas — cuida el acento: essentially /ɪˈsɛnʃəli/, interaction /ˌɪn.təˈɹæk.ʃən/, achievable /əˈt͡ʃivəbəl/, degenerate /dɪˈd͡ʒɛnəɹɪt/, degeneration /dɪˌdʒɛnəˈɹeɪʃən/

Sonidos difíciles para hispanohablantes:

/v/ — no es /b/: los dientes tocan el labio inferior: volunteer /ˌvɑlənˈtɪɹ/, vary /ˈvɛəɹi/, cognitive /ˈkɑɡ.nɪ.tɪv/, novelty /ˈnɑvəlti/, achievable /əˈt͡ʃivəbəl/
/z/ — sonora, no /s/: physically /ˈfɪz.ɪ.kli/, examine /ɪɡˈzæmɪn/, puzzle /ˈpʌzəl/
/dʒ/ — no es la “y” ni la “ch”: degenerate /dɪˈd͡ʒɛnəɹɪt/, degeneration /dɪˌdʒɛnəˈɹeɪʃən/, ravage /ˈɹævɪd͡ʒ/

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
