The next few thousand years brought on the domestication of cows, sheep, horses, and chickens, and the cultivation of wheat, corn, rice, potatoes, and bananas. In contrast, coresidence is relatively low among older adults in Europe and Northern America, where the most common living arrangement of older adults is living with a spouse only or living alone (19).
