Well, it isn't essential to life. But it can be a good bonus...So, my answer is yes. Why? Because you get to share a lot of good time and have a lot of good memories with the one you love. Though sometimes finding that right person can be hard, it is worth the trouble of looking.
For men, probably so. Research studies have actually shown that men in relationships live longer than those that are single. Studies have also shown that single women live longer than those that are in relationships. So is a love life important? Well, if you're a guy and you want to live a long and healthy life, then yes.
