I have always used humor to get me through the day. I make fun of myself, others I'm close to (that I know aren't offended by it) and situations I am in or could be in. It has been something I have done all of my life, my way of dealing with certain situations.
Just three weeks ago, we had a severe thunderstorm pass over us at work with heavy rain, winds that blew trees down in the area and serious lightning that struck a house and set it on fire. The press that we work on has to be shut down anytime there is lightning in the area, to make a long story short, the power grid our plant is plugged into sucks. Anyway, we were cleaning the print cylinders while we were down and one was stuck on the intermediate. As Coop started knocking the print cylinder off, we developed a very high, shrill air leak. Mikey absolutely froze and yelled "Tornado" and pointed to the emergency siren in the pressroom. Mike (close friend I work with) and I just started laughing hysterically about it, and after realizing what it was Mikey started laughing too. Since then, anytime I hear a shrill noise I yell "TORNADOOO". Now, everyone in the pressroom is doing it.
Researchers released information from a study about laughter and RA in 2006. Turns out, I may be doing something right after all. Researchers have found that a good laugh has a positive effect on the immune response of patients with severe rheumatoid arthritis
The article I ran across can be found here. If you don't have an account with Medscape, you can go to Google and type in "Laughter and severe RA" and it will be the first result returned, you can click on it and go straight to it this way without having to log in.
Even if it doesn't help, I will keep on laughing. Like I said earlier, it's just my way of dealing with things. But I know I do feel better laughing vs feeling depressed or mad about something.
