Living to 100 sounds much more appealing when quality of life can be maintained. Your students will enjoy discussing many aspects of aging in this engaging lesson!
This lesson is appropriate for adult English learners at the upper intermediate-advanced levels. It has a discussion phase (to activate schema and build background knowledge), vocabulary study phase, a reading/listening passage followed by reading/listening comprehension questions, and finally some additional role-play activities and a writing exercise. I have used it in individual and large group settings, and found it to be a very flexible and useful resource.
