The race

Two natural gas company service personnel, a senior training supervisor and a young trainee, were out checking meters in a suburban neighborhood. They parked their truck at the end of an alley and worked their way to the other end.

At the last house, a woman looking out her kitchen window watched the two men as they checked her gas meter. When they finished, the senior supervisor, proud of his physical condition, challenged his younger co-worker to a foot race back to their truck.

As they approached the truck, they realized that the woman from the last house they checked was huffing and puffing right behind them. They stopped and asked her what was wrong.

Gasping for breath, she replied, "When I saw two gas men running as hard as you two were, I figured I'd better run, too!"

Galvani's electric fluid

In 1780, Luigi Galvani recorded, "The electric fluid should be considered a means to the nervo-muscular force." He reached this conclusion from work in his laboratory in Bologna, Italy, after a series of experiments and his accidental discovery that muscles are operated by electrical stimulation of nerves. He worked diligently along these lines, but waited for eleven years before he published the results and an ingenious and simple theory. His theory was that of a nervous electric fluid, secreted by the brain, conducted by the nerves, and stored in the muscles. Though his ideas were abandoned by scientists on account of later discoveries, his work opened the way to new research in the physiology of muscle and nerve and pioneered the subject of electrophysiology.
