Protecting Your Brain As You Age (Rebroadcast)

Whether we like it or not, time marches on. And as it does, we age.

One of the most challenging realities for everyone to face in life is that we are all, inevitably, destined to grow old (if we’re lucky, that is).

Aging correlates to a steady decline of functional abilities, both physical and mental. Memory and cognition peak in our early twenties, and we begin a very slow, steady decline of those functions as we near our senior years.

After age 80, many bodily functions – including brain function – seem to have reached the average limit of their operation. So what can we do to preserve our brains for as long as possible?
You know what they say: use it or lose it. The more you think now, the more you will be able to think later, as you age. Activities that are interactive and intellectually rewarding, like having good conversations with people, are not only enjoyable – they’re also good for your brain.

The next time you spend too long talking to someone, lost in a good conversation, there’s your excuse – you were exercising your brain. And by the same token, physical activity and fitness help preserve brain function. After all, your brain is a part of your body – so you have to take care of your body to take care of your brain.

So: think a lot, move a lot, and live a lot if you want to live longer. Drs. Art Markman and Bob Duke give you more of the details.

You’re only as old as you feel: Continued activity – both physical and mental – protects you as you age.

Quinoa: Tanya Kerssen (Ep. 12)

“While no one would argue that Bolivian farmers shouldn’t get a good price for their crop, these trends cannot be ignored—or left up to global market forces. Perhaps most tragic of all is that this boom (and booms are always followed by a bust) is leading the poorest, most vulnerable farmers to degrade their own environment—i.e. the material basis for their very survival and cultural identity—in the name of short-term food security.” Tanya Kerseen “Quinoa: To Buy or Not to Buy…Is This the Right Question?”

In this edition of TSI, Raj Patel, Tom Philpott and Rebecca McInroy talk qunioa with Tanya Kerssen, author of Grabbing Power: The New Struggles for Land, Food, and Democracy in Northern Honduras.
