Interesting scientific facts that will blow your mind.

All bacteria aren't harmful, most of these bacterial are helpful for our body. They produce chemicals that helps us       harness energy and nutrients from our food.

1) The average human body carries ten times more bacterial cells than human cells


   All the bacterial cells living inside you would fill a half-gallon jug or 10 times more bacterial cells in our body    than human cells, according to Carolyn Bohach, a microbiologist at the university of Idaho.
   All bacteria aren't harmful, most of these bacterial are helpful for our body. They produce chemicals that helps us       harness energy and nutrients from our food.

2) Males produce one thousand sperm cells each second 86 million each day.


 
   From relevant reference materials, semen is compound of 3 essential glandular secretion. 75% of ejaculation is built up    by the seminal vesicles, 20% is turn contributes to ejaculatory fluids. Only a maximum of 5% actually comes from    testicles and flows through the spermatic ducts. According to WHO Norms and Standards an ejaculation should contain at    least 39 million sperm cells. In order to achieve this concentration, a man has to remain abstinent for 3 to 5 days.

3) More germs are transferred while shaking hands than kissing.

   We all know, our hands come in contact with many more surfaces than our mouth and therefore carry a variety of germs.
   As a result germs are transferred too while kissing but very less than shaking hands.

4) The reliable pregnancy test in 1960's.


 
   Until the 1960's, the only reliable pregnancy test  was to inject a women's urine into a female African clawed frog. If    the women was pregnant, the frog would ovulate within 12 hours.

5) It takes 8 minutes, 19 seconds for light to travel from the Sun to the Earth.

   In space, light travels at 300,000 kilometers (186,000 miles) per second. Even at this breakneck speed, covering the    150 million odd kilometers (93 million miles) between us and the Sun takes a considerable time. And eight minutes is    still very little compared to the five and a half hours it takes for the Sun’s light to reach Pluto.

6) Do hair and fingernails continue to grow after a person dies?

   After death, the human body dehydrates, as a result the skin start to shrink. This shrinking exposes the parts of the    nails and hair that were once under the skin, causing them to appear longer than before, said Dr. Doris Day, a    dermatologist in New York City and an attending physician at Lenox Hill Hospital, also in New York.
   Typically, fingernails grow about 0.1 millimeters (0.004 inches) a day. But in order to grow, they need glucose — a       simple sugar that helps to power the body.
