Why Do You Have Bolded Words?

I don't hilight anything in my expression of notes, because it's too distracting when i'm reading. I just want to read the text. So if i am skim reading, i can see the bolded words. But apart from that, i don't really bold stuff. I bold them as kind of more like sub categories, which really i could just do as a header, but i don't want to. And any links i have ar quite literally. It's, i i actual regressive e veration. Ling thinks, yes, i do the same thing.
