And to finish the week with some good news. A fine fellow in Manchester's Metropolitan University, sports psychologist Dave Smith to be precise, says his research shows that thinking about doing exercise helps build muscles, even if you never actually get around to actually doing the exercise.

"The brain activity when you imagine doing something vividly, with all the feeling you would get if you did it, is very, very similar to what occurs when you actually do it," he said. Enjoy thinking about it.
