1.) Eyes: You Blink about 20000 times a day.
2.) Hair: Hair grows about .5 mm (.02 in) a
day.
3.) Mouth: You will produce 37,800 l of
saliva in your life.
4.) Cells: There are 50 trillion cells in your
body and 3 billion of them die every minute.
5.) Nerves: Your body has about
13000000000000 nerve calls, transmitting
message at speed of 290 km/hr.
6.) Brain power: You lose 100000 brain cells
every day! The main thing is that you have
100 billion altogether. If surface area of
your brain could be ironed out it would
measure 2090 sq.cm.
7.) Heartbeats: Your heart pumps 13640 L
of blood
around your body in a day. An average
heartbeat rate per minutes of our body is

10.) Tea Or Coffee?
The two main constituents of tea
are“caffeine and tannin”. A tea bag contains
about 40 mg of caffeine and brewed tea
about 30mg. Tea also contains useful
fluorides, volatile oils and Vitamin B.
“Caffeine” is the main constituent of
coffee. A cup of brewed coffee contains
about 80 mg of caffeine and instant
coffee about 60 mg. Medical studies show
that heavy caffeine use (more than 500 mg/
day) may cause harmful physiological
effects. A cup of tea or coffee (without
sugar and milk)contains about 16KJ of
energy.
11.) Fingers: Our fingers are so sensitive
that they can detect a vibration with a
movement of 0.02 cm. Our“finger nails”
grow at the rate of about 0.05 mm in a week
and hair about 3 mm in a week
