Your immune system is basically a grumpy old man with a photographic memory! 📸 When someone coughs near you, your Memory B cells instantly go into battle mode like "I REMEMBER YOU FROM 2018, YOU SNEAKY PATHOGEN!" These specialized lymphocytes store information about previous infections and can recognize invaders they've encountered before. They're basically the immunological equivalent of that neighbor who never forgets that time you accidentally stepped on their flowers. Grudge-holding cellular warriors FTW! 💪🔬
