Eating healthy - living healthy!

Coming through my Google Alerts is this amazing article about healthy eating tips for those at the age of... The article gives some useful pieces of advice about what to eat and HOW to eat to stay healthy when your organism is getting older. I believe that aging people should have an opportunity to learn about what conditions their bodies are undergoing in this time in their lives, and how to deal with that. I guess we can organize classes for the elderly interested in this topic - taking care of their well-being as they are aging. This topic can go along with exercising and other healthy life style choices, such as healthy sleeping and stress management (although the elderly seem not to experience much stress, except for economic concerns). So this is the idea. How do you thing it can be implemented? I would be glad to see your answers in the comments!
