To a certain extent? Yes. There are some people that can control their bodies in incredibly strange ways that don't make a lot of sense.
For instance, my doctor told me that I have some sort of condition where I am incredibly more aware of my body than most people. I don't have great reflexes because my body is almost completely under my concious control. I can make myself sick in less than an hour, can make an area of my body hurt just by thinking about it, and a number of other things that are just *odd*. Getting things to go away is another thing entirely. If I could do that, then I'd actually consider it something to brag about. It's not, though. It makes health conditions seem and feel much worse than they are.
So, it's probably a good thing that most people aren't in control. Frankly, our concious brain just can't handle a lot of what our subconcious deals with. Do you want to control your heartbeat? That would suck, because the second you start playing around with it, you could easily kill yourself.
I'm just talking in terms of physical.. stuff. Lovely word, stuff.
