Deadpool is a shite.
Poets, lovers and philosophers spent centuries pondering and describing the agony of heart break. Lost love, death and failures, despair and disappointment, all could break a person's heart. The pain is literal; many report a heaviness in the chest, difficulties in breathing and a host of other unpleasant physical symptoms. The thoracic discomfort is so keen that for the longest time people thought that heart break actually affects the pumping organ. Since mental distress is often fueled by the stress hormone cortisol, the elevated blood pressure, constricted blood vessels etc manifest into cardiovascular problems for those susceptible to it.
Lament and dirges are written as paeans of tribute to heartbreaks. Emo kids slash their skin, widows throw themselves on funeral pyres (male wishful fantasy), Johnny Walker consumed by the barrel, entire Afghan poppy fields injected into the blood stream, etc etc was committed because emotional pain can be so overwhelming.
And now scientists show that your heartbreak is all in your head.
