As joko says, I think it is pretty much covered in B&S along with all the triviality of some ABers lives.
It's a good suggestion though, perhaps the B&S should be sub divided to include:
1. Life in General (who is the bestest AB/do you fancy me? etc)
2. Relationships (why doesn't my boyfriend answer my text, is infidelity wrong? etc)
3. Health, Fitness and Nutrition (is exercise good, should I diet, are avocados fattening etc)
4. Spirituality
As you can see, these are all covered in B&S but sadly the topic is swamped by no.1, no.4 though would be swamped with people denouncing religion and flogging tree huggers.
