FYI
The U.S. Census Bureau defines middle age from 45 to 64, yet some suggest that 30 is the onset-age, and others refer to 70 as the end of middle age. Realistically, the state of middle age can be better understood if we look for more imaginative ways of examining when it begins and ends than just the number of years. Instead, middle age appears to be a mysterious condition or state of mind.
