- Estimated time of measurement: 2 minutes 43 seconds

PS: Want to increase sales? Cartoon hero Popeye, the Sailorman says: “Easy peasy japanesey!”.
In the 1930’s U.S. spinach growers credited Popeye with a 33% increase in domestic spinach consumption – a welcome boost to an industry during the depression era. The spinach growing town of Crystal City, Texas, even erected a statue of Popeye in 1937.
