My comment about gratitude to elderly is not just limited to our parents / grand parents but to all as they have contributed to the things we enjoy today in one way or another (trees, roads, researches that accumulated knowledge etc are simple examples). So most of those who have positively contributed to the society deserve our gratitude.
(Ofcourse criminals & such negative characters don't deserve such respect simply because they have grey hair).
