The average person walks about 5,000 steps a day, which equates to 73,000 miles by the age of 80. For those in the construction industry or jobs that require being on foot all day, that number could be higher.

Nearly 40 percent of injuries and illnesses, most notably fractures, occur to hands and feet and on average, they result in a median of 32 days away from work to recuperate, according to the Bureau of Labor Statistics. In addition, workers incurred sprains, strains, tears at rate of 40 cases per 10,000 full-time workers, and required a median of 10 days away from work.
