As long as I can remember, I have gathered data to do statistics on everything. From how many goals I scored as a kid, running around playing football in the garden, to the first day of the year the temperature exceeded 20 degrees, so my mum would let me wear shorts to school. In 1996 that day was April 16th.
As an “adult” I do the same thing. Both work-wise when helping customers create data-visualizations to base their decisions on, to when I’m gathering data on all my training to follow my progress towards my various triathlons.
