Working for pay keeps Boomers & Seniors active, engage, healthy, and wealthy. Options include staying in a current position, finding a new position, becoming a contractor/consultant, or starting a company. Add a fifth option: becoming an inventor. Mature adults have been inventing for centuries. They are close to the needs of the 100 million strong boomer/senior market and have the maturity to see the intersection among need, technical possibility, and market acceptance. A major advantage of invention over other options: a continuing stream of income.
