The feeling of being in love can affect the human brain in different ways you never expect.  Loving a person or a thing dearly fills the brains with chemicals and hormones that produce feelings of attachment, obsession and pleasure.

Inspired by Live Science, here are 5 things being in love does to your brain

1.Love makes the brain get a little ‘OCD’

According to LiveScience, the level of the brain chemical serotonin is lowered by love.
