Don’t share your razor!
If you live with a roommate - or a partner - go ahead and share your living space but don’t share razors! Microbiologist Dr. Charles Gerba says that shaving creates tiny nicks and cuts that allow blood and bacteria to be transferred to razors – so if you use someone else’s razor, you’re exposing yourself to their bacteria - as well as blood-borne diseases. Like hepatitis B and C, and even HIV. So never share a razor!
