😮Doctors at Northwestern University kept a man alive without his lungs for 48 hours by using a custom-engineered artificial device.
👏More than two years later, the patient has returned to daily life with excellent lung function.

Just so people know how much of a good lad #Markiplier is:
He's using #IronLung to promote a blood drive and for some of the theatres showing the movie he actually comp'd the concessions.
Plus, the film's success had him in tears of joy.

Recently, despite a long history of supporting the #LGBT+ community, #CloudCo have decided to release a collaboration between @carebearsshow.bsky.social and Harry Potter.
I and a friend of mine have thus sent this letter to CloudCo's President, Chief Growth Officer and CFO.
