I think this could be an ultra helpful book to the right person, but I am not the right person for this book. So much of what the author talks about isn't really appropriate for me.
She discusses fashion: she recommends losing the 4" heels in favor of clogs or kitten heels; I already wear flats and don't really like clogs. She is a little against bathing suits with skirts or wearing uber-tight shape wear such as Spanx. Ironically enough, I just bought 2 new swim suits complete with skirts, and yes, as she says, I did buy them because I'm just giving up. She's kind of right about that one. But I do ALWAYS wear comfortable (read: loose) shape wear, never the uber-tight, have-to-fight-just-to-get-it-on-my-body kind. Not cause I'm trying to actually shape or firm up anything under my skirt, but simply because it's the comfort of shorts with the girly/professional look of a dress. Yes please!
She talks about medical and health issues, such as boob size increasing, sometimes tremendously, like overnight (mine haven't changed in 20 years); she recommends exercise, vitamins, and massage; I am already doing (or trying to do) all of these; she discusses special undies such as Thinx period-proof or Icon for incontinence (ummm, no thank you, not for me).
There's a section on Parenting. I skipped it since there's no kids in my particular picture.
She talks about numerous beauty problems: the need for Latisse to grow eyelashes (I just put on a lot of eyeliner), the need for shampoos & supplements to combat thinning hair (no need for that just yet), the need to start coloring hair (I've been coloring since 22 when I was already tired of plucking the occasional gray hair!), and the need to keep tweezers everywhere for those pesky chin hair (which have not yet made an appearance, thankfully!). She also discusses things such as divorce, 2nd marriages, prenups, stepkids, life insurance, etc.
Who knows, in another 10 years, I may just be the right reader for this book. But for right now, I am not.
