Halfway through the week and in this edition of All Subjects Everything, we talk about the big story in Hollywood and in sexual health this week - Charlie Sheen's public disclosure of having HIV and why we need to have serious conversations about health and responsibility.

Also, TVOne wraps up its fall schedule of Unsung with the greatest hip-hop crooner of all time, the king of hooks, the late Nathaniel Dwayne Hale, a.k.a Nate Dogg. We look back at his impact on rap and r&b and his tragic death ahead of Wednesday night's Unsung premiere.
