What are the benefits/risks of aspirin?

Aspirin is a good antibiotic, everyone knows it. But what people don't know is the risks of asprin. I am one of those people. Care to elaborate?

there is the possibility of too much aspirin used can cause stomach bleeding or ulcers.we know its good for headaches and fever and pain,but some people find it disagreeable,so they should use something like acetaminophen,or ibuprophen.acetaminophen is the lesser of painkillers,and ibuprophen
is a slight bit stronger that i know.
