Charlie's dictum: "All I want to know is where I'm going to die so I’ll never go there."

Many people—some ophthalmologists among them—worry about death. Some worry that they will die too young, missing out on years with loved ones, favorite activities, and the many joys of living.
Others worry that they will die too late, suffering from afflictions, such as dementia, that could leave them with a poor quality of life for many years or a length of time that would exhaust their finances in retirement.

And some worry about both possibilities.
For those who prefer unlimited longevity, there is the strategy attributed to famous businessman Warren Buffett's partner, quoted above.

So if we make the presumption that we will stay reasonably healthy and cognitively intact but cannot live forever, what would be ideal would be to at least know how much time each of us has left upon this green earth. Knowing whether you have 1 year, 10 years, or 30 years before the time comes to "shuffle off this mortal coil," as Hamlet would say, would allow you to get your affairs in order, be sure to accomplish the things you think you are important, and arrange that the last check you write will bounce.
Until recently, it has not been possible to know how long you will live.
