Roy Lee-Faulkner (Letters, 色盒直播S , May 31) suggests there is a research opportunity on the sudden family death phenomenon among students at examination time. I regret to tell him the matter has already been studied and the correlation established (M. Adams, "The dead grandmother/exam syndrome, Annals of Improbable Research , 1995 5 (6), 3-6).
Adams comes up with three possible solutions: stop giving exams; allow only orphans to enrol at universities; or have students lie to their families (for example, as part of registration they must promise not to let any of their relatives know that they are at university).
