why do we fear death?

how is such an action so threatening to so many?

is it really that frightening to leave this world in order to enter one the is even greater?

do we fear the regret of not doing the things we want to do before we die?

if that, is so, then one should live every day as if it were their last, so we can then embrace death with a smile on our face, looking forward to the next world we shall all enter, in due time.
