If the human life expectancy keeps getting bigger will we have to adjust how much a dog year is worth?
Right now most people live to be 70-80 so we say that one human year is about 7 dog years. But if the average life expectancy keeps increasing, won't each human year become worth about 9-10 dog years? If we don't adjust the definition of dog year soon we will have an influx of people who wrongly believe that their dog died early.
