After sending in your application to several shows, it was one called the Trials of Youth that eventually sent you an invitation. As with all the others,the premise seemed less than believable.
Supposedly it was a series of challenges where after each success you were offered increasing rewards or the option to continue. If you choose to continue, your age will be reduced and if you accept a deal along the way or lose a challenge whatever age you currently are you'll be stuck with. But if you win the final challenge you'll get a massive prize and get to pick whatever age you want to be.
Of course you believe none of that to be the case. Much more likely you'll show up for one day before being swapped out for a younger participant who will continue in your place. Not that it really matters while you doubt the big prize money will actually get to you, agreeing to the show comes with an all expenses paid trip to the studio and surrounding city. With that in mind, you send your acceptance. But first who are you?
