We live in a society that puts a lot of effort in medically preserving the old yet at the same time has no use for them.
In older societies the elders held prestigious and deciding positions. They were entrusted with the initiation of adolescents into adulthood, and the education of the children through stories. None of this holds true today. The old live in the margins of society without any purpose.
I have been very fortunate to have had friends of that age group who have taught me through their wisdom, have acted as mentors and have shown me that old age is not to be feared, but is just another phase in life just as important as all the rest.
