The Soybean Car was actually a plastic-bodied car unveiled by Henry Ford on August 13, 1941 at Dearborn Days, an annual community festival. The frame, made of tubular steel, had 14 plastic panels attached to it. The car weighed 2000 lbs., 1000 lbs. lighter than a steel car.
The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system, Gershon says. This multitude of neurons in the enteric nervous system enables us to feel the inner world of our gut and its contents.
The brain and spinal cord are made up of many cells, including neurons and glial cells. Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain. Skin cells live about two or three weeks. Colon cells have it rough: They die off after about four days.
