There is absolutely nothing like a spreadsheet full of data. Being a really sad old barsteward sorry geek, I have one covering decades of my own weight, psa, blood pressure, cholesterol etc - in fact the doc asked for a copy of it. And another one with the location value etc of every family asset - thats the mean minded yorkshireman spreadsheet. Then there is the one of Ferrari prices. And even one of Morgan prices somewhere oin the HDD from when I seriously looked at buying one. See you doubters - I did get that far! And so on and on and on.
Yes, I should get a life. But maybe not a Morgan, well not yet.
