Yes. My illnesses have negatively affected my concentration.
Ability to read a text and process what I am reading. Concentrating on a page in a novel.
It's a major loss in quality of life when you can't read and process what you are reading.
Having to read the same page over and over again without retaining the information.
It has cost me my job.
Worst of all: now I have "all the time in the world" and can't even read a book.
All the wonderful books I always planned on reading "when I have time".
Read, people!
Read as if your life depended on it.
One day you may not be able to anymore.
