Most people don’t experience a significant decline in their mental abilities as they age. There are examples abound of people who have done their best work at a ripe old age – think Michelangelo, artist Grandma Moses, and famous cellist Pablo Casals who at 90 still practiced four or five hours a day. Asked why at his age this was necessary, he responded: “Because I think I am making some progress.”
It’s true there are some differences in learning styles between the age groups. When there’s more in the memory bank, it might take a little longer to retrieve information.
