Hi friends 👋 ,
Happy Friday! I hope you didn’t miss us too much last week. We’re back.

In their place, Ryan said, Zipline is delivering more products like vaccines and supplements that help kids have a healthier childhood instead of simply surviving.
This is huge, that we’re at this point in civilization.
