So, I'm now running with smart watch and it counts my steps. About 16,000 steps for a 10 miler. Now, suppose I averaged a marathon a day, 10 miles in the morning, 10 in the evening and plus let's say I walked 6 miles a day. That would be about 40,000 steps a day. Which is a lot, but doable. I mean, come on. I've had days when I did more than 60,000 steps. So, averaging 40,000 steps a day every day would get you about 15 million steps per year! I'm rounding up a bit, but that's the ballpark number. Now, if you keep doing it for 67 years, you would get to that amazing number, 1 BILLION lifetime steps. Is not it amazing? I'm sure somebody is going to do it, and officially record the number, using those smart watches and other technology. That'd be cool
