Excercise

I am way behind but still committed to getting all 50 in here! Here is
today's excerpt and the three I am missing from this week :)

Daily excercise can have a huge impact on how positive we feel. There are
several reasons why. First, giving our body a regular workout helps reduce
tension and stress. Second, studies have shown that excercise changes our
body's biochemistry. During excercise we produce natural opiates, known as
endorphins, that make us feel happier - hence the famous "runners high".

Finally, regular excercise reduces fat, improves muscle tone, clears the
skin, and makes us feel strong. These changes often lead to a signifigant
increase in self-esteem, a mental state closely linked with happiness.
