COMPLETELY DISTRACTED BENEFICENCE! Walking while working/internet surfing is remarkably simple and an amazingly satisfying...I was able to walk 1.5 mph while working and 2-2.5 mph while surfing with no evident decrease in ability to concentrate and/or perform my tasks. My plan is to stay at this level for a month or two and then try each at greater speeds. Best money I've spent in a long time.
