No... windows are original. We had them revamped a few years ago, from sash to tilt in type (using original glass, wood) and refinished. Much cheaper than replacements. We also have the exterior combination windows with screens that my parents replaced the old storm windows with in the 1970s (or 80s?).
I have always had a problem with standing still. I used to (try to) faint when we had to stand around a science table in high school. I had finished a 24 oz. water yesterday just an hour before. I'll ask the doctor next week. I've watching my diet this week. Maybe I need a little salt? IDK.
