Hey Old Man,
I recently graduated and recieved my license. I am in my very late 30's as well and came from the automotive industry. After a serious injury at work I had to endure reconstructive surgery on my elbow and endure a year of PT. I always admired the nurses and PT's through the whole ordeal and always enjoyed helping others as well, so I decided when I went back to work what I wanted to do.
I worked 40 hours a week and attended school evenings and weekends. I also have a wife and 3 kids, the workload of the schedule was very tough on the family, I missed a lot of the kids school functions and the wife had to take up a lot of the workload around the house also.
But now my wife and kids are proud to say that the Old Man is a nurse.
