I hardly prayed at all since stopping the service to the Borg.. but why not ?
BB, it doesn't have to be an actual prayer. You could do as some of the others here including myself, who visualize Ian's tumors shrinking. Myself (don't laugh. I got this idea from a true story I read once about a lady who did this and her tumors went away), I visualize little pac men eating away Ian's tumors. Heck, I figure if it worked for her, it can't hurt.
