Old man is a song Neil Young wrote and performed for his 1970s album ‘After The Gold Rush.’
I looked the song up on-line, and as for “metrology” (the science of measurement), I saw no good timeline. So I did the measurements and chart.
Thank you Tatum O’Neal, my spiritual sister in November 5th child-ism, in for the suggestion as per twitter 11/14/2011.
