I don't know the website, but we spoke about this in a psych class I took last semester. Some of the main exercises of the mind are doing mathematics, reading, creative thinking(art), and critical thinking. what the mind does, is it rewires and adapts to change. The comparison of the human mind to other muscles involved in physical exercise is a good one. I know that in order to strenghten neural connections you can do things you do with the opposite hand. You got me curious on this topic. If I get more info, I'll post more. Was this helpful?
