Yesterday I met up with a friend and walked through this beautiful park. We had a great walk and I really enjoyed myself. It is always great to catch up with friends. Sadly, I returned with heatstroke. I had all the symptoms: headache, nausea, feeling lightheaded and irritable. What did I do wrong, I forgot my water bottle. When I got home, I drank lots of cool water but it took a while before I felt better. When will I ever learn? This is the third time this has happened in the past two years.
