Dolly Parton: Introduction. Dolly Rebecca Parton is seventy years old. One reason I thought that she would be an interesting subject is that despite her age, she continues to be a prominent figure in country music and a successful entrepreneur. Additionally, I know that her physical development will be abnormal as compared to other members of her cohort because of plastic surgery. I am interested to learn more about her and see how she compares to average in other areas of development.
