The human body is an amazing machine, with some odd quirks.
1. The length of all your blood vessels is really impressive.
If you combine every blood vessel in your body and combine it back to back, they’d make up a length of 96,000 kilometers or 60,000 miles in children and a whopping 100,000 miles in adults.
2. The human nose can detect about 1 trillion smells.
3. The female heart beats faster.
A research by Candian scientists has revealed that the female heart beats faster at about 1.7 — 2.3 hours ahead of the male heart.
4 .At some point, you’ve been a single cell.
This fact is simple but very strange – all of us, at one point, for about half an hour have been nothing more than a single cell.
