I'm 75% right handed, 25% left. I use the mouse with my left hand, but settings are right handed = I left click with my left hand middle finger, right click with my left hand index finger. Kind of a hybrid, I am, eh?
Warmth? Where I live, we have an average yearly temperature of 4-5 degrees Celsius. Without the Gulf Stream the whole of Finland would be tundra. Thus, a global warming would be welcomed here. Growing our own bananas... yes or no to that?
