Laugh together. It's no joke. Laughter not only makes us feel good, but according to research cited in the Canadian Family Physician journal, it releases chemicals associated with bonding. A hearty belly laugh increases oxygen in your blood stream and gives your heart a work out. That releases even more feel-good endorphins. Humor helps us cope with stress; it relieves tension and creates a feeling of intimacy, empathy and understanding. Learning to laugh together will make your marriage better. So, share funny stories with each other. Invite laughter and play into your marriage every day. Go ahead—have a good laugh.
