Shadowing, How to?

Can anyone help me with this? I would like to follow a CRNA around for a day or so to determine what they do and if I want to do it. I am very new to this and have no idea how to approach this. Do I contact the hospital dept. or find new grads or what?

Also, can anyone tell me how they really decided on CRNA as a career choice? Did it appeal due to the income potential or helping patients with pain management or what? I think I might like it but I can't identify exactly what it is that draws me to it.

I am drawn to the medical field due to many reasons, mostly my father's death about 5 years ago. It was very traumatic and I shifted my interests to medical. Being a little older (36) and wanting to finish my undergraduate degreel, I want to work in a fast paced, exciting area. Also, I want to really make a difference to people in some small way while I do this? Am I completely nuts with this????
