It is befitting for a modern person to first examine the question of life's meaning through the lens of the rising generation's needs, the labor and creations of our ancestors, the preservation of global culture, and the advancement of humaneness and science.
Humble acceptance of death from old age — logical and correct, for today there is no solution to significant longevity or beyond. It may well be possible in the future, but today we are at this stage of social evolution and we have what we have. Therefore, there should be no sorrow, only peaceful acceptance. Being realistic is important for a fulfilling and dignified life.
Leading a dignified existence is about finding one's corresponding place: an individual in the societal fabric, a nation within the global collective, and humanity within the cosmic expanse.
