Human's are in certain ways more adaptable than other creatures, I presume more so only at a cognitive level. The cockroach in by far the most adaptable creature within perceivable limits. Guess virus will top this chain. But let me keep this thought with humans.
"Idle mind is a devil's workshop" ... an axiom as it stands today ... "Humans will bring about their own destruction" ... a theory as it stands today ... both are pretty well related
Just came to think about this when my cousin and I had a conversation and he wondered how adaptable we humans are (beware: he is a physisist). Actually empathizing someone's pain (not necessarily just physical). Quite true I realize :-?. Everytime you fail you learn whats blocking your road to success and you move on. Failure when I say, includes everything going wrong. You can get shaken, a los, feel torn, bereft but never beaten until you'v give up.
The psycological strength of a human mind is amazing. Consider pain for e.g. which until a point is difficult. Push the envelope of pain a little further and you get oblivious to the pain, of course surviving past the struggle. Many people use this pain to enter a trance state pushing pain beyond - Body Piercing. Guess this is what
Maybe its the biology / chemistry of the body, which make us impassive to pain. So can we call it - "Pain getting used to our inaction and ceasin / We getting used to pain and move on". I know its possible, coz it works ... I'v done it before :) without realizing it.
Eventually humans either part / lock their pain and move on their journey. With / Without remorse :). But an individuals journey does not stop (no period)
