Over my 50 years as a doctor, I have noticed a strong relationship between a person’s spiritual health and their mental health, and I truly believe you can believe your way to longevity.
There are 18,000 different religious denominations in the United States and countless more spiritual paths and themes. Science says spiritual people of all sorts are more likely to have happier brains, healthier bodies, and longer lifespans. This is because when you focus your mind on God, or any higher power, you are able to get out of yourself, your rut, and your negative thoughts. When you grow the "spiritual center" of your brain, you lower anxiety and depression, enhance social awareness and empathy, and think more clearly.
A person can actually have "spiritual" pathways in the brain that influence moods, sense of self, and how we treat others and see the world and beyond.
