Herinda argues that maintaining this ability would take resources from other activities. But others see no reason why people should not be able to learn a huge number of languages.
Assuming that each language has 20,000 words and that Mezzofanti could remember a word after encountering it once, he would have to learn one word a minute, twelve hours a day for five and a half years!
In the discussion that followed Hudson's publication of N's claims, a reader disputed the Mezzofanti story, saying he found it absolutely preposterous, and pointing out how long it would take to learn 72 languages.
Physicians order CT scans for a number of different reasons including searching for and assessing: tumours, cysts, kidney stones, and bone injuries. Without CT scans, surgeons would have to perform many needless operations.
TSA spokesman Robert Gibbs said a controversial new screening would evolve with travellers' input. Some airline passengers are objecting to the use of revealing full-body scanners and pat-downs for those opting out of scans.

"All the microwaves coming down from space would have been absorbed by clouds or water vapour in the atmosphere before they reached our instruments. That is why we picked Chajnantor," says astronomer Dr. Murdin.
But collecting microwave radiation has one major drawback, as Esteban Illanes of the European Southern Observatory, explains. 'It is absorbed by water. An observatory at sea level would pick up nothing.
The annual rainfall here is negligible - a few drops of moisture scattered yearly on desiccated, empty land. You wouldn't last a day unprotected in this dead zone.
Another way to gather information would be to transport a vessel to and from the planet. The technology exists to do this, but at 20 light years from the Earth, it would take 200 years for astronomers to receive the result.
The next step in finding out the chances of life on the planet would be to measure its light spectrum, a process that would reveal molecular oxygen if it exists. The glare from Gliese 581 makes this impossible, however.
Steven Vogt suggests that Gliese 581g probably has a comfortable area along the midpoint, called the terminator. Any life here would always see the star sitting on the horizon and thus experience eternal sunrise or sunset.
Astronomers estimate that average temperatures on Gliese 581g's star side would be about 71°C and average temperatures on the other much chillier: -34°C.
The comparisons between the Earth and Gliese 581g should not be overstated, however. Even if Gliese 581g can sustain organisms, it would be a very different place to live.
In 2011, 9.5 million Kenyans were affected by severe drought. Few people dreamt that two years later enough water to supply the entire country for seventy years would be discovered beneath the sun-scorched, cracked earth.
From his research, Tommaso thought there could be frescoes of the Roman artist, Pietro Cavallini, hidden under other inferior paintings. Since Cavallini's greatest works had been destroyed, this would be a huge discovery.
Insurance companies insist that stuntmen and stuntwomen do dangerous scenes instead of famous actors because it would cost too much if the stars got injured.
