Just yesterday when I was walking through a mall, I noticed that I was gradually losing sight in my right eye. After about 15 minutes, I could not see out of my right eye. I then was not able to speak properly. I couldn't remember simple words such as "coffee" or how to put a simple sentence together with proper grammar. Instead of ending a word in "ing", I would end it in "une" or "link". I don't know if this was because of the heat (here in Canada, 118 degrees is just a little bit hot), or what ever else. I hope it is nothing too bad.
