You mean we should be able to tell our Left and Right?We should raise our minimum standards
Because I'm concerned while being able to make an L for Left shape with my finger and thumb on my left hand covers that, it leaves me with little options for making an R for Right shape on my right hand as you can't... so I'll have to write an R on the back of that hand but that is impossible, because I write with my right hand and I can't bend my fingers that way!
