Why We Can't Sleep examines the reasons why midlife crises are so prevalent in Generation X women, highlighting poor market conditions, caring for children and elderly parents, and unrelenting discrimination in the workplace.

We're well-versed it the male stereotype of a midlife crisis: a married man with a family wakes up one day and realizes he's not happy with where he is in life.

He'll maybe try doing something adventurous, like sky-diving, buying a bright red Ferrari, or even having an affair.

This is the infamous urban myth of how it goes for men. But generally, we hear less about the struggles of women in this age category.

Women of this age group, known as Generation X, are still withstanding a level of pressure that is gets progressively more difficult for them to bear.

Money worries, unfair compensation at work, and juggling childcare all come into play. Women are also far more likely to have to care for ageing parents.

In her book Why We Can't Sleep: Women's New Midlife Crisis, Ada Calhoun brings to light this essential conversation.
