Here's the science behind why the best lovers are married couples:
1. Dopamine hooks people on sex
2. Dopamine doesn’t have a conscience or a sense of right or wrong
3. Sex is one of the most powerful activities that gives a dopamine rush
4. Sex plus dopamine makes married couples addicted to each other
5. The primary hormone of love is oxytocin
6. Oxytocin and touching often leads to sexual contact and bonding
7. Older couples get the most benefits from oxytocin, touching, and sex
8. Oxytocin bonding is more than an emotional connection for older couples
11. Touching releases the hormones of love when illness gets in the way
