窮則變,變則通,通則久
At the extreme change comes, changing then accessible, accessible then enduring1.
物極必反
Things turn into their opposite when they reach their extreme
三伏練筋, 三九練骨
Training the fascias in the hottest summer days, training the bones in the coldest winter days.
If obviously you can’t escape changes when deeply modifying one’s body, this also remains a truth for each and everyone. Indeed, every day, if not every second, our body changes. It evolves, grows or decays according to our age and reacts to our environment and our intake habits. Even our emotions, when heightened, can have a visible impact, white hairs being the most noticeable one.
