Honolulu Aunty's recent blog post talks about the four things that your brain needs to thrive. I thought it was so interesting. I watched it three times and took notes. I know that my brain has slowed down and isn't as sharp as it used to be.
In short, your brain needs:
2. Omega 3 fats (for neuron tentacles to wrap around)
3. Exercise
4. Challenge
According to brain surgeon Dr. Rahul Jandial, the fourth and most important thing our brain needs is to be challenged. He says that thinking is the ultimate cultivator of the mind and prevents it from becoming dormant.
So now I'm gonna try playing my kalimba again. My eye/hand/brain coordination totally sucked at it even though I practiced and practiced. I eventually lost interest.
But now my intention is not necessarily to get good at it but to challenge my brain trying. Well, we'll see how it goes anyway . . .
