Every time you leave your home, you are at risk of contracting a disease. As a matter of fact, you can contract some diseases even without leaving your home. Some diseases are not lethal, but can be very annoying. Let me talk for example about std. When it comes to many std, it all boils down to same day std testing.

As it is in case of many diseases, the sooner you discover them, the better for you.
