People in their 70s have done ‘The Switch’ and achieved great results. I have found that as long as clients have the cognitive skills and memory to learn the new material presented in the course, they can make great changes. There is a certain amount of computer skills required, as people will need to access emails, watch movies online and attend follow-ups on zoom. Accepting people in their 80s is a case-by-case situation based on assessing cognitive skills and adaptability.
