Okay, guys, here are 3 things you need to know about your wife, girlfriend, mom, sister, and any other important woman in your life.

#1: Women avoid aggression. Anne Campbell teaches psychology at Durham University, and she says women tend to handle stressful situations by looking for ways to make peace. Why? Because they produce higher levels of the bonding hormone oxytocin. But in certain situations, women can be as aggressive as men – they’re just more indirect about it.  For example, instead of saying, “That’s a dumb idea,” they’ll explain why trying something else might be smarter.

The 2nd thing every man should know: Women really are intuitive and they often do know what you’re thinking. A University of Indiana study showed that women are much better than men at interpreting nonverbal cues like body language and facial expressions.

Finally, temperature really matters. For most men, lowering the thermostat 2 degrees makes no difference. But that same temperature change feels like 10 degrees or more to a woman – especially if she’s pregnant. Which is why getting both of you to agree on a thermostat setting is just about impossible.
