Here’s the thing, you just have to market yourself the right way and have the right answers to interview questions. So you are 65, you can easily work many more years, and in today’s work climate it’s typical for people to job hop every 3-5 years. If you can offer a solid 5-10 or more years to a company, there’s no reason not to hire you. You need to leverage your value, experience, stability, no paternity leave to worry about... emphasize that you are able and willing to put in some years of service.
