One side of the human body doesn’t necessarily match the other perfectly. In fact, there is almost always a tiny disparity of size and length in a person’s hands, feet, arms, and legs.
Think about it, a ring may fit on one hand but be tight on the other, a shoe may feel loose on one foot but be comfortably worn on the other. Most of the time these slight discrepancies in size are normal and have no bearing on an individual’s well-being.
