Everyone knows the cliches about being in love — your knees are week, you lose your appetite, you feel butterflies in your stomach. But it turns out that these amorous changes to your body aren't simply the invention of the poets of old. Being in love actually changes you, from the very chemicals in your brain, to the way you act, to the way you physically look. Paying attention to the physical signs from your body that show you're in love may be the only indicator you need that this is more than just a crush or passing fling.
According to CNN, your body on love is a truly amazing thing. For the first few years of the relationship — called the "honeymoon phase" by most experts — your body and mind physically change in measurable ways. From that first date when you notice something different about them to the first time you make love — and all the small moments in between — knowing what is happening to your body can be almost as fascinating as actually falling in love. It turns out that you don't need experts or even your favorite romance novel to tell you when you're in love. The answer can be as simple as looking in a mirror. Here are seven physical signs that you are falling head over heels in love with someone.
