It seems that almost daily, I'm learning of something else that affects health, and ultimately our brain health. In this segment, we're going to open up our minds to all kinds of possibilities. If you are like me, you may have even dismissed some of these in the past. Going back to our initial lesson about Cognitive Reserve and Thresholds, let's look at this section as an opportunity to exercise our brain. As we investigate different things, we may discover some "aha" moments, or we may end up concluding, "I need more evidence." What if we discover that "maybe" this potential assault could contribute to my overall long-term brain health? The next step is to identify actionable tasks. Let's not become overwhelmed, but rather look at each as an opportunity to make minor lifestyle changes. Lots of little changes can add up, reducing the likelihood that we will reach a threshold that results in an observable change in our ability to perform our daily activities and participate in meaningful life.
