Should you tape ceiling cracks?

Homes naturally settle as they age, which can create crevices in the walls and ceilings typically above doors and windows as well as in corners. These superficial hairline cracks can usually be re-taped—but, if the house continues to settle, the cracks are likely to reappear in the same spots.

Does mesh tape crack?
