2012 was our hottest year so far, until this year, i believe. Your location says virginia. Isnt it hotter than hades there? Could you be having mini-strokes? I had one in 2012. I have been very careful ever since not to get overheated. I get a little goofy when i get too hot. Im always a little goofy anyway so its hard to tell the difference. Maybe see a medical dr?
