You want to read about "the grandmother effect" - having a generation older than the current child-bearers is important for long-term survival and knowledge transfer. Other large mammals like orca and elephants do the same.

Modern medication doesn't so much keep very old people alive as get vastly more people through middle age in good condition. My grandmother (born 1916) was elderly at 70 and died a few years later. My parents (born 1946) are older than that now and are generally healthy and busy people.

I don't know where you get the idea that people chug along for decades in misery, though. If you do end up with dementia, your expected lifespan is only a few years.
