I have been doing a lot of reading, about all sorts of things. One thing I've been reading more and more about is exercise. Even light exercise done regularly is very good for your physical health, obviously. It has also been scientifically proven that regular exercise can help treat depression. Today I learned that exercise can help you learn. It helps more neurons grow in the hippocampus of the brain, a structure associated with regulation of emotions and also with memory, especially long-term memory. There's no downside to brain growth, right?
