Are you a sadist?
Let me give you a personal anecdote. I suffered depression and anxiety and fatigue for years. I tried to be active but it made me feel worse. Turns out I had late onset partial biotinidase deficiency. I take biotin, my depression and anxiety are gone and now I can work out like a normal person.
What good does this study do for people like me and the probably hundreds of thousands of people like me? I would in fact it harms people like me because it lays a simple cure over a complex and diverse issue.
