"Well I'm not the kind to live in the past / The years run too short and the days too fast / The things you lean on are the things that don't last" ~ Al Stewart, "Time Passages"
"There's only so much oil in the earth / It's a fact of life - for what it's worth / Something every little girl and boy should know since birth / That there's only so much oil in the earth" ~ Tower of Power, "Only So Much Oil in the Ground"
