If you date someone like you, the likelihood you guys wouldn't last as high. The two of you will think in the same way, and this will lead to confrontation on whose ideas are superior.

Cherish your loved ones. They are all you truly have. 7. Cuddling releases natural pain killers. While cuddling, a hormone called oxytocin is produced. According to a life science blog, a dose of oxytocin decreases headaches significantly, and for some, it even makes the pain go away completely after four hours. Cuddling can actually be a stress-relieving activity as well. It is very personal, and doing it with someone you are not romantically involved with can be frowned at. There are other ways oxytocin is released, besides cuddling. One of the most popular ways is by hogging. A warm embrace can be very comforting. 8.

People at an early age of love have lower levels of serotonin, which is associated with fillings of happiness and well-being and higher levels of cortisol associated with stress. Have you ever felt frustrated while in love because you felt misunderstood? Love makes one vulnerable. It makes you susceptible to hurt if you were previously immune from it. Love makes you emotional, and when you are emotional, you do things based on emotion and not logic. When you are logical, you are more calculated and weigh the odds before making decisions. Love doesn't always let people do that. This may explain why couples fight a lot. 14. Love makes life appear more bright and interesting. When people are in love, fruits taste better, colors appear brighter, and they feel at peace. According to Thought Catalog, researchers looked at a group of people and found out those who were thinking about love said a specific kind of food was sweeter than those thinking about jealousy or something neutral. Love does have its advantages. When you are this way, you don't let things bother you and you genuinely believe that you will figure it out.

The journey of a thousand miles begins with one step. If you love someone, tell them, don't wait until it's too late. So many people have lost the people they loved because they didn't tell them on time. The chances are they love you also but don't know whether you feel the same way about them. 17. Love will literally make you grow. According to the thought catalogue, the act of falling in love is known to have a calming effect on the person's body and mind. This in turn will raise levels of nerve growth for about a year. The process of falling in love and loving someone can help you become more tolerant and patient and dealing with people. People who have been in love before are more mature and open-minded than people who have not because of experience. Falling in love can help you grow mentally and become a far better version of yourself.
