Perhaps I was vague, but I'm not suggesting we start murdering the elderly if that's what you mean. Like everything else in the world, we have a limited amount of resources to spend on healthcare. A disproportionate amount of them are spent extending the lives of people who have already lived a long full life.

If we have to choose between helping someone who's already lived 70 years live another miserable 10 years in a hospital bed hooked up to a machine vs. helping a 30-40 year old person overcome cancer so they can go back to supporting their family, we should do the latter first. Just thinking off the top of my head maybe we could accomplish this with pricing, by making end of life care more expensive and using the cost to subsidize care for younger people.
