Murphy's Law states - "Anything that can go wrong, will go wrong." so why then are you surprised when it happens with your body?

I believe pessimism is an important and healthy lens through which to view our physical journeys, not because I'm encouraging you to wallow in despair and never try, but rather to try your hardest, knowing that you'll always face curveballs in your journey. This is a liberating outlook because it minimises the woe is me mentality, and instead encourages you to keep moving forward amidst the unpredictabiltiy of our physical journeys.
