Midlives [noun]

Definition of Midlives:

middle years

All those stereotypical midlife-crisis movies suddenly make a lot more sense.

The series is about 14 years old — approaching the 20-year “midlife” mark, when Metro rail cars are typically put through a thorough overhaul.

I think it may be because as you hit that midlife period, you’re maybe under a combination of family stress, because parenting is not easy.
