I have outlived a few of the kids that I grew up with in Knowles Village, Liverpool, UK. Two dropped dead at eighteen years of age from heart attacks! They lived across the road from each other and played together. I wonder if it was some exposure that was common to them? Curiously, an entire family of three ladies all got breast cancer just round the corner from them, it killed my friend! A little further up the road another friend dropped dead of brain cancer in her thirties. Always seemed like far too much premature death in such a small area.
