扮臥虎，不必藏龍

time flies quickly within minutes, and life flies quickly within years.
true or false?

nothing more real than the mind, nothing more false than the mind;
the reality is nothing but constructed by the mind.

age, nothing to count yet something accounted, gives me the chance to cherish my health, sort of sad.

times changes many things, yet something left unchanged.
what is it?

i wish i know the answer.
i think i know the answer, likely.
