Valentine's Day is for lovers — but you don't need a romantic soulmate to celebrate. Experts say the holiday is a chance to consider just how rich, diverse and beneficial every form of love is. It can come from family, friends, pets, neighbors or community. Experts also say it's good to have several sources of connection, because one person can't provide all the connection you will need. Love's strong social connections, bonding and support are linked to better health.

Can a six-second kiss each day lead to a more intimate relationship? That's what couples therapists John and Julie Gottman say. They've taught thousands of couples therapists that an elongated kiss can help their clients. It gets couples to slow down and be intentionally affectionate. They say the kiss is long enough to release oxytocin. That's the hormone that some research has shown is responsible for bonding a baby with its mother and building trust by calming down the fear center of the brain. Just create a daily ritual at the same time each day. It might be right before leaving for work, say, or before bedtime. Make sure to savor the time. If it feels like another task, it won't work.
