If all our brain cells were laid end-to-end, it would be 200 million miles long (from here to the Sun and back!)

Death will occur after about 10 days without sleep, while starvation takes a few weeks.

More than 2 million Americans underwent laser vision correction procedures last year.

Johnson & Johnson sprang into action, recalling 31 million bottles of the pain reliever nationwide at a cost of more than $100 million and launching a major PR campaign.

The FBI, Food and Drug Administration (FDA) and law enforcement agencies realized that someone had methodically taken the Tylenol bottles off the shelves at the stores where they were sold, filled the capsules with cyanide and returned them back to the shelves at a later period. Within 3 months, police arrested James Lewis in connection with this crime.

TB kills 8,000 people every day -- it is also the biggest killer of people who are HIV-positive. It's spread through aerosol droplets which are expelled in a cough, sneeze, or spit.

Although the contagious nature of yawning is well established, we know less about why this is so. Researchers are currently giving the topic some serious attention. One theory suggests it's a holdover from a period in evolutionary history when yawning served to coordinate the social behavior of a group of animals. A recent study postulates that contagious yawning could be part of the "neural network involved in empathy."

It is has been reported by different studies that 100,000 to 500,000 newborns are accidentally switched at birth every year -- and given to wrong parents! According to the 1998 Edition of the Tanderberg Report, (an annual medical study by sociologist Dr. Morton Tanderberg, and as reported by Ann Victoria in Weekly World News, p. 22, on 9-8-98), 500,000 or 1 out of every 8 babies born in American hospitals is sent home with the wrong parents.

In many cases, these oversights are caught and corrected within a few days and the babies are returned to their mothers. But on the other end of the scale, Dr. Tanderberg says that in some overcrowded facilities, particularly in large metropolitan areas like New York, Los Angeles and Chicago, the number of switched babies could be considerably higher -- possibly as high as 3 out of 8.

Thus, a work out on a warm, humid day can make you much more susceptible to heat stroke than a hot, dry one -- in other words, it just might be true that "It's not the heat but the humidity that will kill you."

As if things weren't bad enough, doctors in New York City report that a new strain of HIV has been found that appears to resist all current drug cocktails.

But the estimated annual number of AIDS-related deaths in the US fell 14% from 1998-2002 to 16,371 in 2002.

And an impotent form of the HIV virus just might be able to combat any type of cancer. With it's outer coat removed and replaced with one that hunts down P-glycoproteins instead of T-cells, it becomes an "effective carrier for gene therapy".

The differences in taste and color come from their processing.
