Suggestion (Score 1)

A friend of mine is 65 years old and he has faced a similar situation. My suggestion to him was to move a little away from development and explore the possibilities of a Business Analyst role or a technical writer role. A lot of companies are facing this problem where the programmers rely upon detailed specs or comps especially if the development teams are spread out into different countries. In such cases they need a middle man who has experience in development and can successfully transform the business decisions into specs for programmers. During your experience as a developer if you have worked on a specific domain or industry for a long time and know well about it then you can also try to market yourself as a project or product owner. This position is popular now a days and well suited for agile based development life cycles. Hope my suggestion helps.
