This is a great idea. And absolutely legal one. In the society of Biohackers some people claim that they have "biological age" 15-20 years younger. And they even can present a result of the age measurement to prove it. I wish the best luck to this smart person to get his documents corrected. Also, i wish some people will be able to claim that they are old enough to get retirement support from the goverment.
