From Judith Warner:

Today the daughters of these runaway moms, having arrived at the shores of middle age, are taking flight, too. But they’re not, by and large, dumping their husbands. They’re not looking to the job market with expectations of liberation.

Instead, they’re fleeing to yoga, imitating flight in the downward-gazing contortion called the crow position. They’re striving, through exquisite new adventures in internal fine-tuning, to feel more deeply, live more meaningfully, better inhabit each and every moment of each and every day and attain “a more superior, evolved state of being,” as Claire Dederer puts it in her just-published book, "Poser: My Life in Twenty-three Yoga Poses", the latest installment in the burgeoning literature of postboomer-female midlife crisis.

Warner mentions a bunch of books on this topic. Some might be worth reading: Devotion: A Memoir, The Happiness Project: Or, Why I Spent a Year Trying to Sing in the Morning, Clean My Closets, Fight Right, Read Aristotle, and Generally Have More Fun, The Slippery Year: A Meditation on Happily Ever After, and The Gift of an Ordinary Day: A Mother's Memoir. 

I suppose that Eat, Pray, Love would be part of that genre as well. (My review is here.)

While it's great to have the time to get the gym and organize my photo albums, I do think that a balanced life has to be about more than tidy drawers and tight abs.
