Positive thinking helps a lot when you are sick
Personally, I don't believe that one can use their mind to physically move obejects, however I do recall hearing on the radio an interesting tidbit. I can't recall the specifics (it was a few years back) but there was a major study as to the effects of positive thinking while someone was sick. One interesting fact they mentioned was regarding a group of older Jewish men they studied (why they chose Jewish guys, I don't know). Anyway, these researchers noticed that just prior to a major Jewish holiday, the number of older Jewish men who died dropped significantly. Then, right after a major Jewish holiday, the number who died jumped way up. The conclusion? That those who were seriously sick were able to prolong their lives with positive thinking. The desire to see their friends and family during the holidays was so strong, that it kept them going. So there is some connection between the mental and physical side in us.
Anyway, just my 2 cents.
