What's In There??

More than half of people surveyed in a recent study were so clueless about their bodies that they cannot pinpoint the correct location of their heart. Most also do not know how much blood we have, how many teeth are in our mouths or what roles our vital organs perform. Many of the 2,000 respondents questioned by researchers were unable to say what our correct body temperature should be, while nearly 10 percent were unsure of the number of kidneys we have. Additionally, the study found 60 percent could not name their own blood type.
