Let’s go into this more deeply. For example in a pulling contest at a county fair, the first place horse ended up moving a sled weight 4,500 pounds.  The second place finisher pulled 4,000 pounds.  The owners of the two horses decided to see what these horses could pull together.  They hitched them up and found that the team could pull more than 12,000 pounds!  When coupled together, their synergism produced an added 3,500 pounds.

In a small village there was a custom that helped the villagers size up the future happiness of a newly married couple.  After the wedding in the local church, the village women would escort the bride and groom to a nearby forest and stand and watch them cut down a tree.  they would hand the young couple a two-handed bucksaw and ask that they use it to cut the tree down.  the closer the cooperation between the man and wife, the shorter the time it took for the tree to come down.  And the older villagers reasoned that, the shorter the time the happier the couple would be because they had learned that the most valuable lesson of marital lessons-teamwork!
