Brain Plasticity

I've heard so many times that if you "don't use it, you'll use it," your brain will simply stop developing and you won't be able to improve your brain health or thinking. 

Is that true? 

What's the latest research on this?

This week we'll talk about the latest studies on brain plasticity, what it actually is, and mostly, what we can do to help our brains be healthier (because it turns out, we can make a difference in our brain's health!).
