Do you need a good reason to convince your partner to kiss more often? Research has given you a good argument. Kissing not only better for your relationship — it’s also better for your heart. An Arizona State University study found that couples who were told to kiss more often reduced both their stress and cholesterol — and increased their happiness. Take the time to pucker up and feel better.
The thing that I think is the most important is taking moments to express your appreciation to your partner. A thank you or a quick kiss can go a long way toward affirming your relationship and commitment to each other. That’s not hard to do even when you’re juggling insane careers and three kids. – Michael Ian Black
