This article makes me quite happy, mostly because of the whole sometimes-routed-in-reality aspect it gives to Doctor Who. I'm very good at suspending my disbelief, for anything really, I practically look for excuses to suspend my disbelief, but I also do enjoy a bit of realism sprinkled here and there in my various forms of entertainment.
It basically talks about a new drug they've come up with that attacks blood vessels around the adipose in your body (i.e. white fat) and allowing them to metabolize. So, you know, the fat simply walks away?
Blows my mind.
I wouldn't be surprised if the side effects turn out to be alien domination.
