Oh.
I am a dinosaur!
I still like calculating runs created and pythag win theorem out by hand on paper with a pencil...Like I used to do as a kid
I'm something of a physicist, and these days I do most of my derivations on paper, and then use spreadsheets to do the actual calculations. When dealing with upwards of 10,000 data points, the spreadsheets become awfully useful.
In any case, I just became so comfortable with them through my research that I started using them for everyday things, like balancing my budget and keeping track of stats in all the many sports I love.
