Amen! And well put! Can't add anything more to that, and I know it's becoming a much more prevalent attitude with those of us in the 'advancing' years.
I suspect that this reaction to the changes around us is one of God's way of getting us ready to shift off this mortal coil. When we're young and everything is going our way it seems pretty important to us to continue with the status quo, but at this stage the thought of moving on is no where nearly as upsetting!
