When in love:
The heart thumps loudly and rapidly,
The mind becomes disoriented and chaotic,
The pupils dilate and the eyes become round,
The jaws lose strength and the mouth opens wide,
The face, especially the top of the ears and cheeks, flushes,
Oxytocin and dopamine release a flood of pleasure,
The body leans towards the other and copies their motions,
Non-verbal communication takes over and the two talk passionately.
