Fresh country air?

I don't know if this is an aging situation or not.
Sight, sound and smells seem to be in the faint distance most of the time now.

Then things happen. Like seeing something from the corner of my eye not sure if something is there or not. A new noise that needs investigation just to reassure myself that nothing is going to break or blow up. Now, when it comes to smells, blame the dog.

Wrong. It is not the dog. It is the farmer fertilizing his field. The smell is familiar but nothing I can change at this time. Welcome to the country.
