I bought a FitBit a few months ago to help me stay fit. I set a target of 6000 steps a day, a modest total if you're in the prime of life, less so when you're my age.
I manage to achieve this most days, but I can't deny its effect on my daily activities. The FitBit counts steps by the swinging of the arm bearing the watch, so I avoid riding an exercise bike, and make sure that that arm is in motion when using the treadmill.
I'm ruled by a device, just as I am with my computer that nags me to update software programs or run an anti-virus scan. I check the online news and Facebook, consult the weather forecast, interrupt what I'm doing to respond to new email messages.
I've become a slave to digital technology.
