Physicist: Atoms are a little “fuzzy”, so their exact size is a little tricky to define. So taking their size in terms of bond length, and looking at the most common elements in the human body (by mass: 65% oxygen, 18% carbon, and 10% hydrogen), you’ll find that 1kg of person will stretch about 7 trillion km. So an average (80kg) human would extend about 550 trillion km, or about 14 billion loops around the equator, or 1.4 billion trips to the moon, or about 58 light years.
So you can fit a rich man through the eye of a needle, but be sure to coil him up after you string him out. Otherwise the process will take at least 58 years.
