Read more for person biographies

A read more link that allows you to click it to read more of the biography (show the rest of it or read a more detailed version, whichever works best) for those who have longer biographies than others. 

This would help not take up too much space of the page but also give those who are very passionate about detailed biographies a chance to do those without it being too much text to see.

I checked the list of suggestions and couldn't see this one, but if there already is one -- please let me know ^^
