Once again Golden Carers has come to the rescue. I live in a retirement village and calling on my years as a Diversional Therapist I constantly use the Golden Carers for new ideas to run my group in the village. I especially love the Read Aloud Audience Participation activity and I always pick a very shy resident to take a part. It is amazing how much it brings them out of their shell. The quiz always helps keeps their minds active and gives them such a feeling of self worth when they get a correct answer.
