I worked for almost a couple of years on an air ambulance. Before starting I was looking forward to the sense of helping the community. After a short time I just became dispirited with the deplorable conditions in most communities, and the fact that so many of the patients we transported, were ill, either because of their own alcohol consumption, or their guardian's alcohol consumption.
In the end, I found it very dispiriting, and obviously not the job for me.
But good luck if you do it.
