Sabab aad u la yaab leh oo keenta miisaan korodh

Daraasad cusub oo la sameeyay ayaa soo jeedinaysa in wasakhowga hawada muddada dheer la kulmo ay la xiriirto korodhka miisaanka dumarka, gaar ahaan dumarka afartamaadka iyo kontonaad ka dambeeya, sida uu qoray wargeyska New York Post oo soo xiganaya EurekAlert.
