I have figured out how to combine my two 'toys' very productively. The toys to which I refer are my treadmill and my kindle. There is the most perfect spot for parking my kindle on the display of the treadmill and if I increase the font size I can read it while I am running. So now everyday I am supposed to read one chapter of a 'useful' book while I spend 20 minutes on the treadmill. This is working very well because I find that if I don't feel like exercise I probably very much want to read the next chapter of the book and vice versa!
I have to concede that I have given in to the fact that I am totally unfit and am now starting an exercise programme at the walking level so it is easier to read. (I use the marathon training schedule suggested by Tim Noakes in 'Lore of Running'.)
The book that I am reading at the moment is 'Walking in the Dust of Rabbi Jesus: How the Jewish Words of Christ Can Change Your Life' by Lois Tverberg. I thoroughly recommend this book - not only for the interesting reflections on Jewish practices and readings from the Rabbi's, but also for the wonderful contemporary applications of Scripture passages. Very practical.
