How Language Learning Could Protect Your Brain for Life ft. Sophia Smith Galer

⚡ Knowing or learning another language has been shown to reduce the risk of getting dementia. The words we use influence the way we view things like healthcare and death. And the language of food is a treasure trove of history that holds stories of our culture and heritage.

💬 That’s why digital journalist and creator Sophia Smith-Galer is so passionate about the subject. She has an online series called ‘Eatamology’ and is the author of ‘How To Kill A Language’, an exploration of how languages die out, and how we can revive them.

🎧 Stay tuned to find out:

➡ How languages are going extinct at a rapid rate - and why we should save them

➡︎ The deep connection between the language of food and culture

➡︎ How language learning can connect you to your ancestral roots

➡︎ Why being bilingual broadens your vocal abilities

➡︎ How AI is changing the way we speak and the words we use
