One doctor did, too and he found out.

Dr. Edward Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School, says that number didn’t come from a scientific study. Instead it was a marketing tool.
It seems that in 1965 a Japanese company sold a pedometer with the name “10,000 steps meter” (or Manpo-kei). The company chose that number because the Japanese character for 10,000 looks like a person walking.
In fact, according to a study published in Journal of the American Medical Association, just 8,000 steps lowers your risk of dying during the next 10 years, especially from heart disease.
Most people get from 3,000 to 4,000 steps per day just going about their normal day. But if they add another 4,000 steps, they dramatically increase their lifespan. The more you walk, the better the results.
The study found that walking speed didn’t make a difference in mortality. It is how far you walk, not how fast.
