Sheeple Awake!
I would whole heartedly agree with you that old age doesn't automatically mean senility.What makes them senile? Old age doesn't automatically mean senility.
I was responding in part to the Register article that had earlier been quoted and linked to which appeared to suggest there was an added cost in longevity due to the increased likelihood of senility amongst those of prolonged life. The suggestion being that "health freaks" were going to lead to vast numbers of elderly senile persons using up health care resources. My point was that the cost of supporting an obese diabetic requiring a hip replacement who is senile must be considerably more than someone who is merely senile. Plenty of elderly senile people are also grossly overweight and immobile. There also seems to be some evidence that physical activity can reduce the onset of dementia. Unfortunately although obesity often does shorten life it doesn't necessarily result in a "short kill" and often results in prolonged ill health.
