One of them was a mum of two young children, died aged 26. The problem started on the first day of a holiday in Spain. When they got to the hotel, she complained of a bad headache and she had a small lump on the side of her head. Took some tablets but they didn't work. Next day, the lump had gotten larger, so they went to the local hospital where the doctor advised them to return to the UK. Despite lots of tests, xrays, examinations etc, the swelling increased and was getting bigger by the day. After 6 weeks of not knowing what the problem was, she died, and they still don't know what caused the problem.
The same thing happened to my friends' son, who died aged 21. I thought it was odd that they lived within one mile of each other. I mentioned this to his parents, and to the husband of the woman but as far as I know, nothing came of it. A strange world we live in at times.
