I would echo the information about health and exercise.
I started becoming a bit of a health nut around 17 years ago and our brains and bodies are extremely
interconnected with what we eat and exercise and even stress. There are at least 20+ parts of our body that benefit from healthy eating including the heart, minimizing cancer, kidneys, immune system, inflamation, skin, liver and probably the brain. I have been surprised how many of our body systems are connected to healthy eating.
And health is a form of wealth.
