Until!

The air is quiet until it is agitated, The water is calm until it is frustrated, The earth is peaceful until it is violated, The human are wise until they are provoked. The clouds are merrier until these are collided, The fire is fun and pleasant until it is spread, The immunity is good until it is mutated, The human are tolerant until they are contaminated. The childhood is enjoyable until the puberty strikes, The adolescent is seeking fun until the responsibilities arrive, The youth is full of energy until the children are added, The middle age is very fast, until the new nests are formed. The old age is just nice until the sickness knocks, Everything is good and predictable in the life of human, When simplicity and sincerity are followed, Face the challenges, until the solution is found.
