my thoughts..
what are humans for?
to live a happy life?
to succeed in life?
to endure the oldness, pain, disease and suffer death at the end?
in this vulnerable sensitive highly stressed planet, everything is just a result of chemical reactions.
but what can’t be controlled is the soul which is unseen, that if we know how to deal with the inner power, nothing’s too much a matter..
still can’t find the answer to this what are humans for?

Why do turtles live longer?
Because they use less energy, consume small amount of foods, are slow in metabolism,..,move slowly.
A good reference to longevity is that, the lesson turtles give to us is a message from God, that says, a small body lives and acts accordingly to its size and stays in harmony with its surrounding. Never live against its nature as a cold blooded creature. In the contrary, what will happen if the turtles have to run or eat a lot, .., move fast against God’s program for turtles? Living beyond the limit, a challenging daily lives, they cost humans a pandemic.,

the better humans aim, the more discontented it’ll be, the less the challenges, the quieter and tranquil it’ll be..

thank you
