I am a really quick reader compared to most people. Doesn't sound that amazing and it's certainly not unique, but it comes really handy. Always helped me with exams, as I got some precious minutes more to actually work instead of reading. I can go through books and articles really fast. Retention is not amazing, I'd say it's about the same as when most people read in their normal speed.
I really envy the people that can read quickly and retain everything. But I am also content with being relatively quick.
