Let me iterate what Dev said about the Shingles vaccine.
If you have had Chicken Pox, you will likey get it at some point in your life.
Imagine being in never-ending labor, for weeks.
Depends on which nerve it sets, people lose their vision, an ear or can become permanently disfigured.
I never appreciated it, till it was me.
Note to Dev...waiting for chapter #3. Holey moley.
