Continuing with cool stuff out of my research….
When Penicillin was first used in military hospitals the nurses has to administer it by using a special mask to gently blow the fine powder directly into the wound. One QA remembered how stunned she had been one day blowing the Penicillin powder in a wound, leaning in very close to the soldier’s body, when she saw something move. It took a beat before she realized it was his lung expanding and deflating as the man drew breath.
WILD!
