Since it's 2022, it's become very accepting to identifying yourself as whatever you want. If you're a guy but want to be identified as a girl, you can definitely do that. You can even tell people to refer to you using custom pronouns such as "they" and "them" or even "bings" and "bong."
To be honest I feel really young, so I've decided to identify as just being 986 years old. Also, please only refer to me in conjunction to using my preferred trait of "unstoppable."
There are however a few risks when re-identifying yourself. If you for example identify as an apache attack helicopter, you'll almost certainly be sent to war. They'll also expect you to be combat ready and fully functional.
