For those of us of "an advanced age," let's be friggin' realistic here, y'all! I've reached a point in my already long-enough life where I'm comfortable with where I am, who I am, etc. Am I on the verge of embarking on yet another long, tedious, seemingly-perpetual voyage of self-discovery, self-fulfillment, self-improvement? Not bloody likely!
I see this way too often in middle aged men. They are basically done with life and coasting downhill. When we stop growing, we start dying. I feel like my life is just getting to full-speed; I've got at least another 20-30 years of productive life left. Why would I tie myself to someone sitting on the sofa waiting for the grim reaper?
