In this brief response to Joona Räsänen's argument for the coherence and desirability of being able legally to change one's age, I outline a couple of reasons for thinking that the case he makes is deeply flawed. As such, I contend that we have no reason to think that age should be the kind of thing that one should be able to change legally. Moreover, we have at least one good reason for thinking that legal age change would be positively undesirable.
