In the first test suite, Robinson and Reed both have the same age, so I think either the test suite should be improved or Reed's age in the .mat file should be changed.

Keep in mind you have to obtain the position for the older person. This was taught in the max(var) class. Good luck!

Even typing only "Old_name = 2" resuts in size to be 13. What logic and language did you apply for getting size 8?
