I fear if I hurt others knowingly or unknowingly by way of my actions, words and sometimes even thoughts. Because violence is violence whether subtle like thoughts or gross through actions I still would have to face the negative reactions.
Always thinking of a heart attack. My parents both had heart attacks early in life, my mother at 39 and my father at 40something. Even though I am healthy at 55 with slight hypertension, the thought of a heart attack sticks in the back of my mind despite managing a healthy diet and exercise.
