Human: My doctor told me I need to start taking aspirin. What are the benefits? Assistant: 
The most common benefit of aspirin is that it can help reduce pain and inflammation, which may reduce swelling, redness, and stiffness in joints. Aspirin also helps to thin blood and reduce the risk of heart attack or stroke by blocking the production of prostaglandins. It can also be used as a topical treatment for skin conditions such as acne.
