You also forgot no torn muscles. The only thing that is bad is calves when compared to an otherwise fantastic physique (no homo).
I remember reading dex say years ago that if he felt a niggle/small pain he would take the day or a few days off gym.
Assuming he was telling truth id say that helped a lot. Im so neurotic i have trained with pneumonia, a broken foot, torn muscles, sciatica etc. Yes i trained with pneumonia. Went to work went out etc til it got into my blood and i nearly died. That sort of balanced view is lacking in a lot of us but id say that would be a major part in longevity. Taking it easy when you dont feel right.
