Very beautiful article. If more people would have this "rational" mindset about what works in terms of diet and lifestyle I think the area of fitness and health would be a more peaceful space. I feel there's a lot of arguing and ridiculing each other's arguments.
My girlfriend is a cancer survivor too. And she too has such an amazing attitude towards her body. Even though she is still experiencing symptoms of fatigue and gets exhausted quickly, she is proud about how her body survived and is healing.
I wish you lot of strength on your journey.
