If they answer yes, it won’t expire because the time doesn’t go backwards. I could also store the date exactly 18 years before the answer is given as a pseudo-DoB, that could be used, later on, to, for example, prove that the user is at least 21 for whatever reason. Most importantly, this would ensure that the user doesn’t give any unnecessary identifying information to the system.
look! a pyramid! must be aliens!
