I am an engineer who worked for a number of companies, had my own once and finished career working for Dept. opf the Navy. My specialty was in experimental anti-submarine warfare projects.

Retirement is an opportunity to be a kid again and do something entirely different, maybe something you always wanted to do. In my case, I became a street medic and worked for a few years in Richmond Va, one of the most violent cities in the country. I am still doing it although in a quieter rural environment. Very satisfying.

The key is ... education. Find something you really want to do and go to school. Get a certification (or whatever) and do it right. Bullskitting your way into a job will eventually bite you in the a$$ every time.
