I had this crazy thought when I was a kid. 

“Before I die, is it possible to cover every piece of land on this planet just by walking?”

Let’s do a rough math.

If you consider only the landmass, it is 148.94 million sq km. Consider a 1 sq m bounding box. Let’s assume that this box represents our position and moves at 1 sq m per second. Ignore constraints like sleep, food, and crossing the ocean.

To cover the entire landmass, it would take us approximately 4722.85 millenia 😦
