I just walked for a frisking 15 hours in the past 3 days. My legs are dying and stuff. Save meh

Fact of the chapter:
An average person walks as much as walking 5 times around the equator during their whole lifetime.

Joke of the chapter:
My grandpa started walking 5 miles a day when he turned 60.
He's now 97 and we don't know where the hell he is.
