Walking the walk

I may not be an exercise fanatic (far from it..), but I do engage in a lot of walking on a daily basis, I will have you know. Bristol is a city with a huge number of hills so I tend to walking up a gradient almost everywhere I go. In addition to this I walk a lot of stairs as the faculty and library buildings are like Escher engravings of houses with stairs running off stairs leading off stairs onto stairs and so on. Fit? Perhaps not terribly, but happy none-the-less..
