Ambrosia, a company that injects young people’s blood into older people, says it is now up and running in five American cities, the company tells Business Insider. Filling your aged veins with one liter of a younger person’s blood costs $8,000 — and two liters is a steal at $12,000.

The big picture: This whole blood-replacement thing is marketed as an anti-aging treatment. But, as Business Insider notes, there’s essentially no evidence it has any medical benefit, and it has raised plenty of red flags along the way. Ambrosia recently completed a clinical trial of its procedure, but hasn’t published the results yet.

In the coming decades, seniors will work long past 65

The developed world is aging — in the coming decades, the U.S., Europe and nations across Asia will have hundreds of millions more people who are 60 and older.

The big picture: Much of this coming avalanche of senior citizens won't be playing pinochle at retirement homes. Instead, if technology optimists are correct that advanced economies will continue to need massive numbers of workers despite automation, hiring will continue to be tight. Because they have the most experience, older employees are going to be in huge demand and will work a decade and perhaps longer past 65.
