How far does my computer mouse move?
PAUL MOORE, CAMBRIDGE
I can’t tell you how far your mouse moves, but I can tell you the distance that mine moved because I installed a little app that measured every last centimetre. In one continuous hour of working, my mouse moved 123.76 metres. For an entire week, my mouse moved 2.5 kilometres. I clicked my mouse 10,695 times in the same period. Scale it up to a year and my mouse would travel the distance from Bristol to Birmingham! It’s a fun thing to try, but be aware some apps like this steal your passwords, so don’t use them while working on anything important – my measurements were made under controlled conditions. PB
