I don't naturally have much of a smell. You do. So I'm not sure he could track me. Are you asking me if air devil technology is possible in our world? What I'm saying is that the our range of what we can smell, even if you enhanced our sense of smell, there's only so many different things we can smell and differentiate. And so if you have people who use the same detergent or something, like there's a lot of ways where people could end up smelling fairly similar.
