Ona could see the passion and enthusiasium the boy had for records. He thought long and hard about some records Ona could have achieved. By having her be the oldest person alive, he would have had her friendship longer. Once they realized there were many people ahead of her on the list, he came up with her being the oldest licensed driver. Ona also became excited as this gave her a goal. This was something she and the boy could work on togeher which helped cement their friendship. After the boy died, she was able to keep the goal alive and honor their friendship. I think this was a doable goal. She may not make it to the oldest person alive, but she was able to achieve other records. I don't have any desire myself to go for any records.
