1. The average red blood
cell lives for 120 days.
2. There are 2.5 trillion
(give or take) of red blood cells in your body at any moment. To maintain this
number, about two and a half million new ones need to be produced every second
by your bone marrow. That's like a new population of the city of Toronto every
second.
3. Considering all the
tissues and cells in your body, 25 million new cells are being produced each
second. That's a little less than the population of Canada - every second!
4. A red blood cell can
circumnavigate your body in under 20 seconds.
5. Nerve Impulses travel at
over 400 km/hr (249 mi/hr).
6. A sneeze generates a wind
of 166 km/hr (100 mi/hr), and a cough moves out at 100 km/hr (60 mi/hr).
7. Our heart beats around
100,00 times every day or about 30 million times in a year.
8. Our blood is on a

9. Our eyes can distinguish
up to ten million colour surfaces and take in more information than the largest
telescope known to man.
10. Our lungs inhale over
two million litres of air every day, without even thinking. Their surface area is large enough to cover
one side of a tennis court.
11. We give birth to over
200 billion red cells every day.
12. When we touch something,
we send a message to our brain at 124 mph
13. We exercise at least 36
muscles when we smile.
14. We are about 70 percent
water.
15. We make around 1 to 1.6
litres of saliva a day.
16. Our nose is our personal
air-conditioning system: it warms cold air, cools hot air and filters
impurities.
17. In one square inch of
our hand we have nine feet of blood vessels, 600 pain sensors, 9000 nerve
endings, 36 heat sensors and 75 pressure sensors.
18. We have copper, zinc,
cobalt, calcium, manganese, phosphates, nickel and silicon in our bodies.
