There are a lot of factors that help to regulate our overall health and wellness. If we are content in our lives and relationships, we are more likely to be healthy.

If we exercise and eat well, we reap the benefits in our mind and body. Also, as recent studies by Ted Kaptchuck and others show, if we take medications or supplements, even if they're nothing but rice powder and sugar, we can feel better.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about why taking placebos somehow makes us feel healthier.

SpaceX is gearing up to launch its Falcon Heavy rocket from Kennedy Space Center this afternoon. The rocket is the most powerful to be launched in the U.S. since the Saturn V rocket, which carried NASA’s first astronauts to the moon. SpaceX says the launch will carry the largest payload of any rocket since Saturn V in 1973.

The test launch will also carry Musk’s personal Tesla Roadster into space as payload, which will (ideally) careen into orbit around Mars while playing David Bowie's "Space Oddity." 

Because we know how things work, sometimes we think we understand why these things work as they do. That can be a problem.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the difference between "how" and "why" knowledge, and why it's important to recognize what you really need to know.

What causes cities to grow and prosper – or not? Why does one side defeat another in war? Those are complex situations with a lot of contributing factors. One factor that history doesn’t often point out is weather.

When thinking about how we present ourselves, at a job interview, for example, we might think that the more good stuff we tell the prospective employer, the better. That's not really the case, however. Our best assets can be overshadowed by the average of all we present.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about The Presenter's Paradox, and how we can put our best foot forward.
