The fundamental tragedy of life
Here is the fundamental tragedy of life. We are brought into existence, and the desire to continue to exist is an intrinsic property that is hard wired by natural design in each individual: we desire and struggle for our existence and we fear and fight death. However, it is also a hard fact that, as time goes, individual physical body will inevitably move away from the pre-assumed equilibrium state, and cease to exist. We might, through our struggle, to somewhat prolong our existence, but physically, and mentally as a consequence, we will all decompose therefore cease to exist in the long run.
To make it worse, the occurrence of a threatening physical condition is conveyed to the individual mind by a design through negatives (suffering). We could find ways to avoid short term shifting away from that equilibrium state, therefore to reduce the need of a frequent unpleasant reminder of bad physical situations (this is to say, to reduce the human suffering)，but human suffering as the default design for the purpose of stimulating actions for individual physical preservation is intrinsic and can only be reduced to certain degree.
Within this fundamental tragedy, there is also a fundamental justice and fairness of life: whatever in store for an individual, he/she only have this much to enjoy, this much to suffer, and this much to experience. At the end, we are all dead in less than, say at the moment, one hundred years of time.
