That's for sure!People also carry weight very differently, so 20 pounds might look obese on one person, but on someone else, it might look like teddy bear fluff.
I remember this one teenager on the job who was what is currently classified as morbidly obese. It looked like he was wearing a life preserver around his waist. But he was always consciously aware of where he was relative to his surroundings, he maneuvered his bulk with grace and agility in a tight, fast-moving McDonald's grill area and he always got his job done.
Then there are the slobs - fat and thin - who never pay any attention to their surroundings, are always in the way and play on their phones constantly.
