Being terrified of aging and mortality is a sign of immature mind.

The earlier people start seriously think about their future decades and inevitable death, the better for them. Everyone has the change to prepare their body and mind for a long-lasting and fulfilling life (e.g. avoid unhealthy habits and nurture healthy ones).

Some philosophers maintain that properly cultivated awareness about one's future death is one of the main factors that help to grow as a person and to build a proper attitude to life's joys and sorrows.

Maybe these aging filters are net positive for humanity, as they nudge towards more conscious life style.
