Questioning?!

Interesting, the root word of question is quest.
So, what is a quest? Don Quitoxe?
A quest, basically means to search, the act of seeking. When one is on a quest, one is seeking an answer.
As in science, one must act the correct question to get the answer one is seeking.
Life, I would surmise is a quest. Looking for an answer/or answers. Maybe, there's more than one question.?
We're born and learn how to survive. That's the first thing that comes to mind--survival.
Is that the basic question? As a human being, how do I survive. But, why survive?
We're born, we live, we die. Very finite, no ifs ands or buts, everybody does.
One theory for survival is the continuation of the species. I must survive, and procreate. That is human. If human beings did not procreate the species would die. OK, but what about people, couples who do not have children. Do they not, then have a reason for survival?
But, I digress. My questioning is personal:

I am a 57 year old male, who has done his spiecies
responsible thing. Procreation.
The offspring have been raised and are now adults.
My original plan was to spend the rest of my life with
Suzanne, what-ever that meant. But, now I am faced with a
changed plan--there is no plan.

What am I doing for the rest of my life on this earth?
