Science has no answers to stop old-age and death

There is no superior power which can check the cruel hands of death.
Even in the days of so-called scientific advancement of knowledge, there is no remedial measure either for old age or for death.

Wherever there is the influence of eternal time, there is this set of tribulations, namely birth, disease, old age and death, and all of them are invincible.

(SB 1.13.19 - Purport)
