I would say, well, how much do you eat each day? I would add them all up to figure out how much they eat in the year. And maybe family member A eats 813 hours in a year. Family member B ate, I don't know, 732 hours in the year. And so you see the general notion that I will be collecting multiple data points from the different family members, and they're very well, and in fact, there's very likely to be variation in that. In fact, I might even see variation from year to year. Person A is probably going to need a different number of hours in the next year.
