A few fitness tidbits for your consideration:

• Active people have 25 percent fewer colds than couch potatoes.
• Several species of small animals live longer if they regularly consume fewer calories than usual.  Recent studies show that this might also be true of humans.  Yes, going hungry once in a while might be good for you.
• A recent Mayo Clinic study shows that people who have a positive outlook on life are generally healthier than people who have a dark outlook.  I’d like to get more information on this one.  I wonder if the study really shows that unhealthy people have a dark outlook on life.  That is, which is the cause and which is the effect?
• Finally, people who have short tempers might be more sensitive to pain.  Their bodies produce low levels of endrogenous opioids (like beta-endorphin), the brain chemicals that suppress pain.
