Laughter is a Healthy thing to do
Every now and again I get something in the email from my friends and it makes me laugh and when I laugh at that moment I can tell you it has a way of uplifting my spirit ( Jazzes my energy level) and at the point in time I am as positive as you can get...now it seems to me if we can laugh more and bitch less we all would be happier and healthier as a result...Now for some of you it may seem inconceivable that this could be true....Think about it for a moment it takes more muscles in your face to frown then to smile and when you laugh you get more oxygen deep into your system ( which is always good) and there is a an occurrence in your Mind to go from mundane or negative to at least for some of you neutral and for others positive (People often store negative emotions, such as anger, sadness and fear, rather than expressing them. Laughter provides a way for these emotions to be harmlessly released. Laughter is cathartic. That's why some people who are upset or stressed out go to a funny movie or a comedy club, so they can laugh the negative emotions away (these negative emotions, when held inside, can cause biochemical changes that can affect our bodies).

laughter reduces levels of certain stress hormones. In doing this, laughter provides a safety valve that shuts off the flow of stress hormones and the fight-or-flight compounds that swing into action in our bodies when we experience stress, anger or hostility. These stress hormones suppress the immune system, increase the number of blood platelets (which can cause obstructions in arteries) and raise blood pressure. When we're laughing, natural killer cells that destroy tumors and viruses increase, as do Gamma-interferon (a disease-fighting protein), T-cells, which are a major part of the immune response, and B-cells, which make disease-destroying antibodies.
Laughter may lead to hiccuping and coughing, which clears the respiratory tract by dislodging mucous plugs. Laughter also increases the concentration of salivary immunoglobulin A, which defends against infectious organisms entering through the respiratory tract.
What may surprise you even more is the fact that researchers estimate that laughing 100 times is equal to 10 minutes on the rowing machine or 15 minutes on an exercise bike. Laughing can be a total body workout! Blood pressure is lowered, and there is an increase in vascular blood flow and in oxygenation of the blood, which further assists healing. Laughter also gives your diaphragm and abdominal, respiratory, facial, leg and back muscles a workout. That's why you often feel exhausted after a long bout of laughter -- you've just had an aerobic workout
