How many steps does the average person make in a day, and how many times does a person walk the circumference of the earth in a lifetime?

There are far better mathematicians on this site than me, but here goes anyway: |
The site below gives the circumference of the Earth at the equator as 24,901.55 miles.
As there are 5,280 feet in a mile, this equates to 131,480,184 feet.
Given an average length of pace of 2.5 feet (various sites) and rounding down to 2 feet to allow for times when we are either very old or very young and take shorter paces, this equates to 65,740,092 paces round the Earth.
Assuming a lifespan of 75 years, ignoring leap years, and taking 5,000 as a conservative estimate for the average number of steps in a day from Kerry's figures above (to allow for being very old and very young when we may not take so many steps in a day) we come to a figure of 136,875,000 paces in a lifetime.
Divide this by the number of paces required to go round the Earth, and we come to a figure of 2.08.
So, allowing for all the assumptions, roundings and guesstimations above, the 'average' person will walk round the world twice in his or her lifetime.
