Novelty can be hugely important. It can be anxiety provoking for some people and you've got to be careful about that. But one of the things that we know is curiosity and novelty are associated with activity in these areas of brain that release and process dopamine. Dopamine is a modulator that, as I mentioned, promotes plasticity. Some work even suggests that if you, let's say, put an animal in a box and you let it explore this box that it's never been in before, its brain gets flooded with dopamine. Then if you give it some task, now it will be better at remembering the things that it was doing for this task. So in other words, that dopamine can have this spreading effect. So I think that is something that will improve people's memory, potentially. And also I think that kind of engagement is just good for people in general. There's also just a lot of value in seeing and feeling that you're learning. It can get very easy to get into a rut and then feel like everything is the same. Sometimes you lose that curiosity as you get older. I know because I see this in my colleagues sometimes and I'll say, Hey, what are the findings in your lab that you're most excited about? And they'll say, Nothing's new, it's all the same, we're all just rehashing the same stuff. And I find that so depressing because it is like my whole business is curiosity and I am a big believer in the power of curiosity." On The Mind-Body Connection "If you want to improve your cognitive functioning, or you want to retain your cognitive functioning over time and you want protect your brain health, consider that your brain is the seed of the mind and it is a part of your body. I think a lot of people have this idea of somehow I am my mind, and then my brain is separate. And it's not. It is all connected. What this means is that if you're not taking care of your mental health, your emotional health your physical health, it's going to affect your cognition and possibly increase your risk for dementia.... If you want to get in to the positives, sleep and exercise are very important." On Prioritizing & Memory "So at a minimum you want to prioritize, right? So I don't hear people telling me, Boy,
