lol i hate folded bills, if im putting notes in my wallet i prefer to make sure they are give or take level and "opened"
another habit i have is i used to open a can in two stages, pop the pressure then open in one move but nowadays i try to do a single flick open and push back in one move.
occasionally when im driving i'll put my left hand at 9 and my right hand palm down on my lap, else i'll use two hands, resting on my wheel cover bumps with my thumbs curled inside underneath the inner thumb supports of the 10-and-2 position ( i hold my wheel at 9 and 3 ) a mate of mine used to hold his car one handed with his right hand in the door handle when swinging his ass end out lol, it scared me a little but to him it was only natural.
