I'd hardly say those deaths are unexpected. And planned/unplanned deaths is another discussion entirely. They're quite normal for the most part, and in fact significantly lower than the rate of death in most other species. Human beings benefit because of resource use and culture change. Imagine if we double the lifespan of the majority of people on earth how insane things would quickly become. Or are we only talking about doubling the lifespan of those who can afford it? In which case wouldn't it be better to focus these research resources into raising universal quality of life (ie developing malaria drugs), rather than further raising QoL for the rich in the 1st world?
