I haven't heard of him before and I am sorry he is sick but goodness. Fascinating that he thinks willpower is the key. I don't get that. Does he really think that? oh I insist ye virus leave my body now - oh goodness that lacks any sort of commonsense.
My experience is that willpower is one of the first things disabled when it gets critical. Example. One time I had a tick on me, didn't know it, didn't know ticks made me sick either but I was in anaphylactic shock and unable to move a limb through will power at all but up goes my arm with deadly accuracy ripping the tick out from the top of my head.
Or my father - he never showed me affection when the choice was his but there he is on his death bed and I walk in the door and his arms rise up to hug me and it was real but completely involuntary - he was unable to make his arms move at all by then.
