Rainer Maria Rilke's comparison of love to the measles may initially seem strange, but upon closer examination, it reveals a deeper truth about the intensity of love as one grows older. Just as the measles can be more severe in adults, Rilke suggests that love can also become more intense and consuming with age. This metaphor highlights the idea that the emotions and experiences of love can have a profound impact on individuals as they mature, influencing their thoughts, actions, and overall well-being. It implies that love can be both exhilarating and overwhelming, especially as one gains more life experience and perspective.
