A young man in the UK, who once performed on stage with Irish boyband Westlife, dropped dead of a heart attack despite being in good health.
Gary Anderson's family thought he was fit and healthy, but he died suddenly one afternoon whilst working at his computer. After fighting for tests to be had, it transpired that the 31-year-old had an undiagnosed heart condition - Brugada Syndrome - which they now know runs in the family.
His mum Valerie, 64, and his youngest sister Jacqui, 29, from Cramlington, Northumberland, say that Gary died for them to live - as since his tragic death, Valerie was diagnosed with the rare condition and wears a pacemaker, while Jacqui is believed to be borderline, with further monitoring required.
