I use a tissue to clean my ears before I use them and take off the little silicon plug thingy every long once in a while and wash them in my hand with some dish soap
You have to convince yourself its ok to murder a pedestrian, my friends grandpa hit someone at a crosswalk that way, luckily they were ok and kept on walking but its always better to let your car get up to temp and defrost the windows and wipe down the side windows and mirrors
