BSL-4

A laboratory that contains the deadliest viruses known to mankind. These viruses are Ebola, Marburg, Lassa, Hanta, Smallpox, Crimean hemorrhagic fever, Argentinean and Bolivian hemorrhagic fevers. So any disease that makes you bleed to death, you should wear a positive pressure suit not to catch it.

Walking into a BSL-4 lab without a space suit is basically a suicidal act.

Sub 4 Sub

Many desperate YouTubers with fewer than a thousand subscribers on their channel will subscribe to any channel just to gain an extra subscriber in exchange. This is regardless of how terrible the videos are. Unfortunately, some YouTubers who do have great talent, creativity, and wonderful video quality sink to the bottom of the Mariana Trench as hundreds of boring videos surface the Pacific islands.

Sub 4 Sub? I can't wait to see the latest crap!
