I suspect that focusing on the physical could/would be disastrous for the Golden Years experience, what with the body being in the process of dying.
Look at birth as a merging of the physical/flesh with the spirit/Self/soul – which continues thru childhood onto adulthood.
I see the Golden Years as a unmixing/detaching/disengaging of the physical/flesh with the spirit/Self/soul – with the spirit/Self/soul now at its highest point in the physical world (for me anyway) – which continues until the body dies.
My Golden Years started at 62, and each year has gotten better—until 78+ so far. An *AMAZING* time of life!
