I'm the same Mags. I can look at the goriest things and actually be quite fascinated... until I consider the injury from the victims perspective... my imagination/empathy is too strong. I also have naturally low blood pressure so the slightest bit of stress will often make me feel light-headed. I have considered training to be a nurse but I think I would have too much empathy and be too prone to fainting. I always dealt with dissecting animals and organs at school really easily... actually I am very fascinated by anatomy... it's a shame my empathy section of my brain short-circuits my thought processes when somebody i care about is involved. Maybe it gets easier with practise???
