Phylum Chordata is the only phylum where all the members have a  backbone.   However, there is more to it than that, especially given that there  are two invertebrate châ¦ordate groups - Urochordata (tunicates) and  Cephalachordata (lancelets) - whose backbone is not in the form of  actual vertebrae.
The answer. Anger is a normal, healthy emotion that we all experience at times. Like any other emotion, anger exists on a continuum with varying degrees of severity. The range of emotions may include minor annoyance, irritation or frustration, all the way up to fury or rage.
Attempting to control your anger only allows the anger to control you. We suggest an opposite approach where you place less emphasis on the need to control. Tightening your muscles, clenching your fists, and shouting fiery expletives merely makes your body heavier; it obstructs the free flow of energy.
