(NECN/YNN) - Here's a woman who knows how to keep going strong, well into her older years.
90-year-old Freddie Anderson is the best-known ski instructor at her school in Rotterdam, New York.
She and her daughter run the independent school. With nearly a century of experience on the slopes, she says she loves teaching others.
Anderson says she's on the hill every day, even with her titanium knee -- teaching young and old alike.
