<p>I heard that this causes axons to tear, thus killing an unspecified amount of brain cells.</p>
<p>I don’t headbang or anything of the sort-- But I do nod my head to say yes. In addition, I now simultaneously feel a fear of accidentally shaking my head as well as an urge to try it.</p>
<p>So what’s the definitive answer?</p>
<p>Edit: I meant to say “kill brain cells.” Although maybe killing brain cells and brain damage are the same thing.</p>
