[font=Tahoma][size=10.5pt]So you see [u]physical [color=red](illness)[/color] can[/u] have psychological [color=red](causes)[/color]. Now we just have time to introduce another interesting example of [b]interaction [/b]between the mind and the body – [b]placebos[/b]. Placebos, [u]maybe you’re heard them called[/u] [color=blue]<sugar> [/color]pills—are [color=blue]<harmless>[/color] [color=red](substances)[/color]—not always sugar—[u]that are[/u] used [color=red](routinely)[/color] on [u]group [color=red](of[/color][/u][color=red] sick) [/color]people in experiments. These experiments test the [b]effectiveness[/b] of new drugs. One group is given the new drug, the other group is given a placebo, and the [u]results are[/u] measured.[/size][/font].mbs9\ j

[font=Tahoma][size=10.5pt]As you may guess, some of the people who receive the new drugs get better. [b]Surprisingly[/b], however, some of the placebo group also gets better. Why? Well, it’s an interesting question, one which doctors can’t quite answer. Some of the group may have gotten better [color=red](on their own)[/color], without any treatment at all, but research has shown that the very [color=red]([u]act of[/u])[/color] taking [color=red](medication)[/color] that you think will make you better often does [u]make you feel[/u] better. Have you ever taken an [color=red](aspirin) [/color]and felt better in five minutes? Aspirin doesn’t work that fast, does it? [color=blue]<Basically>[/color], if you believe you will get better—sometimes you do. [/size][/font]
