Life is all about change, and change produces stress. But there is good stress (eustress) and bad stress (distress). You wouldn’t want to get rid of the good stress associated with birthdays, weddings, vacations and all the enjoyable things in life. You wouldn’t want to avoid the stress that helps protect you – tells you to remove your hand if you put it down on a hot stove burner or prepares you to run away from a threat. You cannot get rid of acute stress (like accidents) and for the most part human beings handle acute stress episodes fairly well; they are short term and when they are over and done with you recover from them. The stress you want to avoid as much as possible is chronic, low level stress – that’s the stress that hurts health-wise.
Short answer: You can’t, so build resilience
