Obvious jokes about STDs aside, love can burn you. Well, not really burning you, but pretty close.
At least that what your brain thinks. As it turns out, your brain treats emotional hurt the same as physical hurt. Because of this, you may actually hurt your lover without laying a hand on them (that they can prove in court).
Science found this by taking some people who had experienced breakups within the previous six months, and sort of burned their hands, and apparently their brains reacted the same way as when they looked at pictures of their exes.
So if you’ve been feeling down, you’re in pain, or somehow you’ve gotten a significant sickness or cold, feel free to blame your ex.
