If you don't solve this problem, janma-mrtyu-jara-vyadhi (birth, death, old age, and disease), then any form of life, there will be problems. Even if you are elevated to the heavenly planets, there are also problems. Indra is not very happy there, the king of heavenly planet. Although the higher planets, the duration of life, the standard of civilization, standard of comforts many, many thousand times greater than here, but the same problem - janma-mrtyu-jara-vyadhi - is there. You cannot avoid it.
