As a small business owner in IT managed services, age absolutely does NOT matter to me. I'm more interested in a person's willingness to continue to learn and not stay stagnant. If you are in your 80s and have continued to learn on your own and want to stay engaged, I can do the heavy lifting ... that's no problem, welcome aboard. Attitude, experience, and wisdom trump youth every time. My marketing director is 25 years older than I am and I can constantly learn from him because he stays on the cutting edge and subscribes to lifelong learning. My brother has a mechanical engineer on his payroll that is 92 years old and is an extremely talented and creative guy. He can design something on paper in a mere fraction of the time it would take a lesser experienced engineer to do. Don't ever make the mistake of judging someone on age - judge on attitudes.
