I have my doubts about...

Does love actually exist?

 It is said that love does not exist.

Starting from a biological analysis, love is a reaction caused by a neurochemical effect, obviously in the brain.

So yes there is, but not as many people paint it as a "magic", but as an effect. It is nothing more than a feeling caused by chemical reactions in your brain, bone in your brain. It has nothing to do with the heart, the liver or anything like that.
