Not your ordinary hand to hand combat
.Consider holding hands with your spouse when you have a tough decision, disagreement or important matter to discuss. The physical closeness may help you remember to be calm in your approach and understanding in your listening.
There may even be other side effects like keeping your voice at a moderate level, looking each other in the eye, giving each other your complete attention, etc. Can you think of others?
