After recently becoming the proud owner of an all signing all dancing fitbit (other brands are available) I find myself drawn to checking it all the time. Have I hit the magic 10k steps before work, have I climbed the equivalent amount of stairs to the Eiffel tower before lunch etc etc. I do sometimes question its accuracy, eg; Saturday motorbike ride,  I managed a whopping 24,000 steps (good effort) whilst sitting down. This led me to believe momentarily that the only real benefit of these sexy little straps is to taunt your connections through the app, however the below happily proves me wrong again!!!!!! Wear it, it may just save your life one day.
