Career Choice [Official?]

I have decided, Lord willing and in good faith that I will not utterly collapse while completing my degree, to become...

A nurse!

The reason for this is multi-fold:
1) I feel that it's wrong that many people in developed nations have health care at their fingertips and I would be honored to be able to provide health care to people in less developed countries or underprivileged people or developed nations. In other words, I want to be the hands of feet of Jesus and giving medical attention to those who wouldn't normally get it would be a great way to do that.
2) I know that if I stay in the States or come back the the states at any time, I'm pretty much guaranteed at job somewhere.
