I agree with this as a general statement. The usual trend is that we learn so many new things while growing up. We attend school everyday. We get our degrees, get our jobs, and then we specialize. We are not so much learning any more as honing our already acquired skill set to mastery. There is a difference. Lifelong learning outside of your skill set is much better for your brain and decreases the likelihood of developing Alzheimer's and other age-related cognitive illnesses. So having the mindset to learn something new at 85 is amazing and I hope to always retain that thirst for knowledge. It's good for you!
