Suffering is how Life tells you that you are resisting or misperceiving what is real and true. It is the way Life suggests that you are not in harmony with what is.
It is not just a person's physical constitution, their intellegence, their education, or even their social conditioning that enables them to withstand hardship. Much more significant is their inner development. And while some may be able to survive through sheer willpower, the ones who suffer the least are those who have a high degree of patience and courage in the face of adversity.
Now this, monks, is the noble truth of suffering: birth is suffering, aging is suffering, illness is suffering, death is suffering; union with what is displeasing is suffering; seperation from what is pleasing is suffering... in brief, the five aggregates subject to clinging are suffering.
There is superstition in science quite as much as there is superstition in theology, and it is all the more dangerous because those suffering from it are profoundly convinced that they are freeing themselves from all superstition.
