Love and sex feel great, but do they affect the way we think? You bet, and the news is good. A 2009 study showed that people in love tend to think more long-term, which boosts their creativity. During sex, by comparison, people tend to focus on the present, which helps analytical thinking.
We already knew sex and love had great physical benefits, and now we know there are mental benefits, too. Not that you needed another reason to get under the covers and get busy!
