Health and safety

I was listening to my local BBC radio station yesterday, and they had a guy on to promote his book.

He's a doctor, working at Alder Hey Children's hospital, and he reckons that people that make lifestyle choices that cause them to be ill should not be treated on the NHS.

He advanced a financial case, but really, he was taking a moral position.

You see, he was thinking about stuff like this...

But doesn't the same argument apply to the things below too?
