Growing up, I had a great aunt who I will refer to as Aunt D.  Aunt D. grew up in the Great Depression, saw all three of her brothers drafted to fight in WW II, and outlived her husband.  My cousins and I loved to go to her house because she was so much fun.  She would cook us hot dogs, and we would play Bingo.  She ran through the yard with sparklers on July 4^th.  Aunt D. rode a go-cart through the yard on her 80^th birthday.  She rode on the back of a Harley Davidson motorcycle when she was well over 80.  As she grew older, she began to complain about her friends.  They would go on senior outings to the local amusement park, and her friends would only shop and watch shows.  Aunt D. wanted to ride the roller coasters! Did Aunt D. age gracefully?  Exactly what does it mean to age gracefully?
