Since biologically assigned gender is now considered  outmoded and unfair, I propose we now attack  chronologically imposed ageism. 

As with the nuisance of biology constructs,  having one's age assigned is arbitrary and contrary to human values.  

We are all, after all, only as old as we feel. 

Getting rid of the straitjacket chronologically assigned age will have the added benefits of removing the crimes of pedophilia, child marriage, etc from society.   

As well,  we can all get OAS whenever we want and  all criminals can claim that they feel they are juvenile offenders.........thus reducing their sentences, and reducing the costs to taxpayers of their imprisonment. 

we all win.
