Emotions - health effects

I read the following in a local magazine.

• Brain contracts with increase in age and leads to forgetfulness. However, physical exercise compared to metal exercise and social activities will help to keep the brain active.
• Happiness and heart are linked. More happiness increases heart beats and one will not get sleep. I experience this, when I got good marks (beyond my expectations) in my XII standard, engineering final year, receipt of appointment letter (25 years ago) in the organization of my choice where I am continuing still and my first promotion. Similar is my experience, I was under pressure. 
• Anger affects liver which leads to generation of bile juices and headache. Blood pressure too raises.
• Tension, stress affects lungs and one feels suffocation.
• Depression/sorrow reduces energy levels which affects lungs and leads to associated respiratory problems.
• Fear affects kidneys and one looses control over urination.
• Threat affects heart and at higher levels it can affect kidneys also.
