This is an interesting topic worth talking about. We always get tired and feel dizzy after working hard for a day. The signals from our body are often misunderstood as if there was something wrong with our brain. So, we intentionally look for some ways to get our brain stronger and better. The first thing that usually comes into our mind is food. Among a variety of food, the brain-shaped food is our priority. Fortunately, there is one kind of snacks that really looks like our brains. You might have guessed what I’m talking about: walnuts. When we crack open their tough shells, the nuts inside often gives us an impression that we just open one's head. No matter how scary a walnut looks like, it's really tasty. There is a beverage brand called Six Walnuts. It means that if we eat six walnuts every day, our brain will be very healthy. Maybe eating walnuts gives us a hint that it can help us strengthen our brain. Each time I eat a few, I really feel relaxed and powerful.
