Lost data

I have lost count of the number of times I have been seated round about middle and off as you look at this Picture taken today in Saundersfoot carrying out valuable research. I realised today that it has been a wasted effort because I neglected to keep the proper records.
What happens is that Ann goes round the shops and I sit quite near to the whelk stall as was and sneer internally at the passers by as I await her return. In itself this would not be a valuable contribution to the advancement of science. However in addition to sneering I got into the habit of assessing each person who crossed an invisible line running from the whelk stall as was to me. I put them into one of two pigeon holes. The slim and the obese. Those of indeterminate size I mentally discard.
So I sit there counting the obese on the fingers of my right hand and the slim on the fingers of my left hand and when I get to more than five I perform a strange little mental trick that I cannot explain that enables me to continue counting.
How valuable this data would have been had I written it down when Ann turned up instead of immediately forgetting it and saying something like "Where have you been?"
I realised today too with even greater regret that were I to observe my present self crossing the line from where the whelk stall was to the bench where I sit I would have no option but to count myself on my right hand.
