This is a conversation base lesson that begins with a discussion on the aging process and getting older in general. Before the discussion takes place, lexis for giving opinions, agreeing and disagreeing is reviewed. After the conversation is a text titled "Has the Human Lifespan Hit the Ceiling?" This can either be used in class as a reading activity or assigned for homework. I assigned it for homework when teaching this lesson. Next, idioms with the word 'hit' are introduced and practiced in a shared storytelling game where students take turns telling a story line by line using the newly learned idioms. Finally, the first, second and third conditional structures are reviewed and practiced through speaking exercises.
