While it sounds like a great way to save the NHS money by getting people to become healthier problems will arise in practice.

Anybody who smokes and doesn't want to quit can simply resume smoking after the test... Just like how drug addicts who are forced into detox usually return to using after they are released.

With obese patients the idea is even worse because if they simply diet to lose the weight they will end up losing a combination of fat and muscle, which lowers their metabolism.

There is! The car you are looking for is called a Used Car and as an added bonus it is significantly cheaper than any new car on the market!

Well as a photographer shooting weddings I generally carry 8 SD cards on me at any given time. When I load them into my SD case I put them all label up to signify that they are empty and ready to go. As I go through cars during the course of a day I put my spent cards back into the case label down to signify that they are no longer empty and need to be downloaded to the computer.

Most of my colleagues use the same method with their SD or compact flash cards.
