One of my favorite sites, io9.com has an excellent discussion of many myths related to the “love hormone” oxytocin at http://io9.com/5606765/myths-about-the-love-hormone-oxytocin-that-could-ruin-your-love-life which is really well worth the read.  Seriously, take a peek and see how yet again political agenda has coopted science.

All the best,
