TV Review: Ten Years Younger: The Challenge "Age ain't nothing but a number," sang the grammatical illiterate Aaliyah. And with that double negative, she agreed with the production team behind Ten Years Younger: The Challenge. See, age is more than a number, it's a bloody great stick that can be used to beat a drab, middle-aged lady into agreeing to have her nose caved in and sanded down all in the name of entertaining you. You turd.
