Six interesting facts about human body, from the highest IQ to the maximum friends we can make

Human body is a unique creation of God in itself. Science have employed many years to understand the human brain and the human abilities but still there is lot of scope for research hitherto.

Human body grow and develops throughout the life but there are certain limits to development.

Here are a few facts regarding human body that you would be surprised to know,

The tallest height human body can achieve

8 Feet 11.1 Inches. In the 1930s, Robert Pershing Wadlow, also known as the Giant of Illinois, reached this world record due to an overactive pituitary gland. His towering stature severely stressed his circulatory system (he couldn’t feel his feet) and placed structural pressure on his bones (he wore braces when he walked).

As a result of these physical limitations, engineer Thomas Samaras estimates that while the average human has grown taller due to better nutrition, we will eventually level off at about seven feet. His studies have also found that every inch above five feet shaves 1.3 years off a lifespan—though others dispute this claim.

Maximum weight it is able to lift

1,000 Pounds

The world’s strongest weight lifters can hoist 1,000 pounds—but Todd Schroeder, a biokinesiologist at the University of Southern California, thinks they’re hesitant to do so. Our brains limit the number of muscle fibers activated at any time to keep us from getting hurt.

“Turn that safety off, and you can produce a lot more force,” Schroeder says. He thinks optimal training, including mental, may help athletes tap as much as 20 percent more strength.

Smartest it can get

IQ of 198

This honor goes to Abdesselam Jelloul, who set this record on a 2012 adult IQ test. But a few prodigies aside, if your score approaches Einstein’s 160, you’re probably at humanity’s upper reaches.

Maximum friends a human can make

150 Friends

We’re not talking about Facebook friends, but real ones that you can depend on. With that criteria, 150 is the max, says Robin Dunbar, a psychologist at the University of Oxford. Dunbar examined census data on tribal groups, which averaged out at 148 members.

Maximum period it endures without sleep

11 Days

In 1964, Randy Gardner, a 17-year-old in San Diego, woke up at 6 a.m. to start his science project: an attempt to break the world record for days without sleep. He succeeded. Gardner made it to 11 days while William Dement, a Stanford University psychiatrist, monitored his vitals. Gardner remained lucid, albeit irritable.

Since then, studies have shown that rats deprived of shut-eye will die within 30 days, and a rare disease called fatal familial insomnia, which stops people from dozing off at all, causes death in a few months to a few years.

Maximum period it can endure without food

382 Days

Of course, this feat is easier to accomplish if you’re obese to start with, which was the case with “Patient A.B.” The 27-year-old, under observation at the University of Dundee in Scotland, weighed 456 pounds when he started his fast in the 1973 study.

With a diet of purely non-caloric food such as yeast and multivitamins, he dropped to 180 by the time the study ended, more than a year later. Needless to say: Don’t try this at home.
