That's because when we look at an elderly, we subconsciously think of our own elders. Being raised to respect and love elder people, it's normal for us to easily become emotionally attached to ANY elderly. So we take care of them as how we would be taking care of our own grandparents.

Without the old people, we won't be here. Personally, without my grandparents, my parents won't be here, therefore, I won't be here. So I owe my life to my parents but most of all, to my grandparents. Old people anywhere represents my grandparents.
