Does a high temperature help fight infection?

TemperatureFor the most part no, so far as we know. Only two types of infections have been shown to be inhibited in their growth by the sorts of temperature the body reaches during a fever, and these are the two venereal diseases syphilis and gonorrhea. My temperature always seems low, does this mean that i am never at my best?

No it is quite normal for your temperature  to run a little lower than average. In fact, the normal range of temperature is quite wide-anything between 35.6C-37.2C (96F-99F). If you are exercising quite hard, does the temperature of your body go up? Yes. But there is a wide difference between the temperatures of various parts of the body. Doctors often refer to the core temperature, and this means the presumed by taking the rectal temperature. The core temperature of someone doing hard exercise may be very much higher than normal, with figures as high as 39C (102F).

Is it true that twins exhibit the same personality traits?

Twins who have been brought up together, whether they are identical or fraternal, tend to develop different personality traits, most probably as a way of expressing and establishing their independence. One twin might become more studious, the other more sociable.

What is interesting however is that pairs of monozyggotic twins (identical twins, formed from a single ovum) exhibit almost identical personality traits if they are bought up separately. Many studies have been made recently on twins separated at, or shortly after, birth. The results are a strong argument for the idea that many personality traits are indeed inherited.
