I have a data frame called 'bio' that has the columns 'full name of contestant', 'id', 'age', 'season number', and 'personality type'. From this data frame, I want to find the contestant who was the oldest at the time of their season. Then, I want to use this information to select their row from another data frame called 'TV Show' that has the columns 'full name of contestant', 'id', 'age', 'season number', 'occupation', and 'gender'.
