The most common cause of color blindness is an inherited fault in the development of one or more of the three sets of color sensing cones in the eye. Males are more likely to be color blind than females, as the genes responsible for the most common forms of color blindness are on the X chromosome. As females have two X chromosomes, a defect in one is typically compensated for by the other, while males only have one X chromosome.

Condiment packets are convenient, but how long do they last? Because of their high salt and acidity, not much can grow in ketchup, mustard or relish in a sealed packet. If they are kept in a cool place, they should last even longer. Heinz places the shelf life of condiment packets at 15 months to 2 years. By the time a consumer gets a condiment packet, it has already been manufactured, shipped to a warehouse, distributor, restaurant, and then sold to a diner, all before it finally lands in the bottom of the desk drawer.
