What do Grapefruit, Doctor Who, and Brown Hair have in common?

Ever wonder or care why you can't have grapefruit with certain medications?  I didn't think so.  So don't read this:

Grapefruit’s culprit chemical does not interact directly with your pills. Instead, it binds to an enzyme in your intestinal tract known as CYP3A4, which reduces the absorption of certain medications. When grapefruit juice blocks the enzyme, it’s easier for the medication to pass from your gut to your bloodstream. Blood levels will rise faster and higher than normal, and in some cases the abnormally high levels can be dangerous.

 I refused to watch Doctor Who after David Tennant left, because I saw the new guy as a usurper.  No one could ever be as great a Doctor as David Tennant.  I still believe that, but last night I finally gave in and watched an episode with the new guy, Matt Smith.  I was so pleased to see that The Doctor is still The Doctor, and I rediscovered my love for him.

I dyed my hair brown

Brown hair, silly lips
