Diet, physical activity and human interaction is imperative for a healthy brain and body. Staring at a television is probably one of the worst things to do to a brain, we don’t have one those things in our home. I’m never bored, always busy with something whether I’m out and about meeting strangers, swimming, walking in the hills leaning about various species or helping the wife with her business. I like the challenge of strategy for the day and week ahead. Poor diet is probably the worst thing for the brain as well, sugar, high amounts of carbohydrates, alcohol and tobacco, all brain poison.
