What do the mating habits of animals have to do with people? I skipped this chapter because it seriously annoyed me. There is much more interesting information later in the book, and starting with this almost made me skip the whole book.

Sometimes this book is a 5, and sometimes it is a 1.

Good things:
Fun facts! Jazz lovers are 30% more sexually active than other people.
Clear Presentation.
Occasionally humorous.
Included information on same-sex married couples.

Bad things:
Some parts were just so "duh" - Of course being married makes men live longer.
Seems to be a lot more personal than she wants to admit. She shares a bit about her own seemingly recent divorce.
Used the word "notably" WAY too often.
While included info on same-sex marriage, incredulity implied in findings was borderline offensive.

Take aways:
It reaffirmed by belief that it doesn't matter what we fight about, just how we fight about it. Disagreements are healthy and necessary.
Don't criticize how each other does something. Be it parenting, cleaning, etc - just be grateful for the help. Don't let control or power issues cloud your support of one another.
Snoring can cause major health issues for everyone. It can even cause hearing loss or sleep deprivation in the partner!
Know the difference between complaint, criticism and contempt.
