I remember when hubby and I met a couple when we moved to Toledo OH. She was owner of the house. She had recently moved there (with its fenced-in lot) from a three-acre place out in the country.
She couldn't understand why her VERY healthy TWENTY year old German shepherd was now aging so much quicker since leaving the country.
It seems that ignorance is bliss but only when you are ALREADY living under the right conditions.
