We all get butterflies when we finally ask That Person to be our girlfriend or boyfriend. Or, for some of us, uncontrollable heart palpitations and a feeling of impending death.
Finally, one Reddit user has provided evidence of this bodily sensation - by wearing a Fitbit as they asked out a girl.
As you can see, their beats-per-minute go drastically up, before dipping back down.
Importantly, what was the answer? According to the comments, a big fat yes.
Judging by the colour of that line, it's a good fat-burning method, too - which is the most important lesson of today.
The fear of rejection is a magical thing.
