How To Catch a Liar

There’s no such thing as a “tell”. For example, when people look up, fidget or stutter they might just be nervous, and not exactly lying. However, because we rely on the truth to make our culture go round, it might make our lives easier if we could just spot a liar out of the crowd.

As it turns out you can tell if people are telling the truth or not, but it takes some skill, time and knowledge.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about lying, and a new study that reveals a more accurate way to catch someone in a lie.

Holidays: The Fountain of Youth?

For many of us, Thanksgiving means spending time with our families, carrying out traditions that we’ve practiced for years.

While it can be very stressful, messy, and challenging to spend time with family members you don’t see very often, it can also be a beautiful time of re-centering.

Traditions serve a psychological function. By repeating the same traditional activity with the same group of people over the years, we construct a chronological record of who we’ve been before – and who we are now. It’s a hidden way of staying in touch with the consistent elements of our identities, and it allows us to track ourselves as we develop and change.

Traditions give us an opportunity to become psychologically close to the person that we used to be in childhood, or adolescence – or even as recently as last year. And that’s something to be thankful for.

As always, Drs. Bob Duke and Art Markman are carving it up.

How To Protect Your Brain As You Age

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.
