Then astrophysicist Neil deGrasse Tyson discusses the secrets of the universe, why we're here, and if there's intelligent life out there.

By the way, who define us as intelligent? That's an important question. We define ourselves as intelligent. So, would we be intelligent to an alien species who has the technology to jet between galaxies?

Then, how self-fulfilling prophecies work in your everyday life, and understanding pain, why we feel it, what it does, and what can make pain more painful.

We learn throughout our life that when we go to the doctor, pain is going to happen. And so, when we expect pain, we start generating an experience of pain even before the actual external stimuli has hit our skin.

All this today on something you should know.

Since it's a new year, why not make this the year of you? Like everyone, I'm sure you have problems, concerns, feelings you don't know what to do with, and a great way to really take charge and deal with those very personal concerns is through therapy with talk space.

Now, I decided a long time ago that rather than just let life happen, you've got to take charge, and often that's hard to do all by yourself. It always helps to talk with someone. And with talk space, you get a trained license professional.

I recommend talk space because you can sign up online, get a personalized match with a provider, typically within 48 hours. You can text, video, or send voice messages to your therapist, and it's just incredibly convenient to have virtual sessions from the comfort of your home.

And talk space is secure and private. It's just between you and your therapist. And they accept insurance. Talk spaces in network with most major insurers.

In short, members on average pay a $20 copay or less, but you don't have to have insurance. As a listener of this podcast, you'll get $100 off your first month with talk space.
