I knew I’d officially become a “longevity influencer” when a company called Generation Lab offered me the chance to write about—and even receive—their new rejuvenation treatment.

This wasn’t just any antiaging treatment, either. A company fact sheet says that it “blocks the systemic spread of aging in the bloodstream, reawakens the body’s own repair mechanism and restores health and youth to multiple tissues.”

The approach is based on research by Generation Lab’s irascible scientific founder, Irina Conboy. She found that joining the circulatory systems of old and young mice improved the old animals’ ability to heal from injury.

Conboy now says she has found a combination of two existing drugs that can produce youthful effects without the need for any bodily fluid exchange. But Generation Lab won’t reveal what the drugs are, making the proposition hard to take seriously.

How to sign up for a virtual power plant—and decide whether you should

Your thermostat may not look like a power plant. Neither does your electric vehicle, home battery, or HVAC system. But utility and energy companies increasingly want to treat them like one.

In exchange, participants receive a discount on their energy bills and, in some cases, a signing bonus.

Here’s how to sign up for a VPP—and decide whether it’s worth it.
