When John Green Explains How Everything Links Back To TB

In a hilarious recurring joke across his videos, author and creator John Green became obsessed with connecting practically every historical event back to tuberculosis.
.
Green explained that throughout human history, tuberculosis was so ridiculously widespread that it quietly shaped art, literature, fashion, and even major geopolitical events without people realizing it. Whether discussing 19th-century poetry, architectural trends, or world leaders, Green would inevitably pivot the entire conversation right back to his favorite infectious disease.

Seeing John Green somehow connect every single historical topic back to tuberculosis with absolute passion is pure gold. #johngreen #vlogbrothers #crashcourse #history #behindthescenes #funny #viral #funnymoments #shorts #comedy #interview #educational.
