Skilled

I think these guys knew what they were doing. From lots of pieces of all shapes and sizes, they quickly put it together. 

I decided that I needed to strengthen some leg muscles to see if that helps my knee and, having an aversion to real cycling and no inclination to go to a Gym, I invested in an exercise bike. We went to try some out and today the chosen one arrived. It has a screen with all sorts of numbers on it, but what I like best of all is the ledge - just right for a book.
