Is it worth the fight - YES
Sometimes I wonder why I fight so hard? Should we just let nature have its way with us and allow for Darwinian selection and allow the weak to be removed?
It only takes a micro second or so for me to negate those feelings and get back into the fight - because that is what life is for all of us - a journey maybe but one w many hills and hurdles - to me it is worth it when I feel good and when I make someone laugh, when I see a response in the eyes of another person and when I feel needed and loved. That is worth the pain and that is why science and medicine are so important to me - allowing us all to feel good at least some times and during those maybe brief moments of peace / feel part of something bigger.
