Okay I'm glad that most of you are at least on board with washing your hands after no 2, 'cause theres a really nasty bacteria called Helicobacter pylori which is transmitted by fecal matter ingestion... yum. I've had it, it causes acid reflux and ulcers, not fun! I have to urge you all, wash your hands every time you go to a washroom.
A few guys have said that they haven't gotten sick and haven't washed their hands, therefore its fine not to. Just because you didn't get sick, doesn't mean anything, I have been washing my hands and I haven't been sick for a year, but it may be a coincidence and is in no way proof.
Some of you have argued that our immune system will take care of any bacteria. True, we have an immune system, a kick ass one, but I also think we have a pretty decent brain and, please choose to use it too! Washing hands simply makes sense, especially in a public bathroom, I cringe every time I see or hear a guy leave the bathroom without washing his hands.
