You can do a lot just by deciding that&#x27;s what&#x27;s happening. Spent years with a mystery vomiting illness. Wallowed in my misery. One day, decided &quot;I&#x27;m better now&quot; - and lo and fucking behold I&#x27;ve been fine for a year.<p>Anecdotal, sure, but either the illness or the cure was in my head.<p>Also... Rasputin and the Romanovs - he could stop Alexei&#x27;s bleeding (haemophilia) with a <i>phone call</i>, when physicians had had no joy - the boy took after his father and was deeply devout.<p>Anyway. Interesting stuff.
