sporting can be dangerous ... my uncle (lived in new zealand) played football (or soccer, i dont remember, its 15 yars ago) ... he scored ... screamed with joy .. fell down on the field .. and didnt move again ... people thought he made a joke (including his wife) .. as he often did ... but after some time it seemed it was for real .. a heart attack as well .. after that all his brothers had to go to the hospital for heart exams
