Wow... I believe I fall into these studies findings as do many others. Unfortunately not all studies are 100% correct due to lack of honesty with test subjects or an agenda. I can honestly admit that I know I might not the sharpest tool in the shed but I can and have been the neighborhood go to for plumbing, electrical issues and numerous other issues that's occurred over 27 years and have yet to burn down or cause a flood. I'm a happy guy with a big heart and I seem to be getting along just fine!
