I have never fainted in my life (all 42 years of it) and ironically enough at lunchtime today while at work I thought to myself 'I am going to faint' - just felt really lightheaded and woozy for no reason whatsoever. I work in a busy doctor's surgery so wasn't too bothered about anyone picking me up if I fell down - but I went outside and took some deep breaths of fresh air and felt a lot better. Never gave it a second thought after that till I read your blog . . . strange day!
