Barry Marshall is the man behind the discovery of helicobacter pylori.Helicobacter pylori is a bacteria that causes peptic ulsers in the stomach.So technically he proved that ulsers are not caused by stress,spicy food and too much acid.Most people thought that bacteria could not live in the acidic stomach but he soo proved them wrong!! Symptoms of stomach ulcers include nausea,vommiting and etc..Wanna know how he discovered it!! He tried it on lab mice but it couldn't work because it's a human bacteria so he drank the bacteria himself!!!! Damn that was one hell of a risk he took just to prove himself right. He was obviously awarded the nobel prize for his discovery!! guess what!!! I met him!!!! hehe =)
