I remember inhaling helium from a balloon for fun once and got a sudden sting in my head when i was 12 or so. Made me wonder if it's really that harmless as everyone claims to.

This video is sensationalist hyperbole. Long, drawn out video clickbait. His ridiculous speaking style reminds me of Robert Downey Jr's role in Natural Born Killers.
