THE DOCTOR SAYS THAT YOU HAVE "A TEMPERATURE" SO YOU MUST BE ILL!
WRONG!! WELL.......of course you may be ill but...
You would really be in big trouble if you did NOT have a temperature. Of course when people say that you have a temperature they mean a HIGH temperature (ie higher than normal).
Body temperature is about 37 degrees Celcius (or 98.4 F). Temperature is a measure of speeds at which the molecules are moving. (physicists: its really a measure of their average kinetic energy). so slower molecules means lower temperature.
If you had NO temperature your molecules would not be moving...you would be at a temperature which we call "absolute zero" - there is NO temperature colder than this. On the Celcius scale Absolute zero is at -273!!
