I half-agree. As a tall person, Spirit's legroom isn't great, but it's bearable for short flights. However, for fats, it might be impossible to fit, because their giant asses/thighs push them forward into the seat and then the giant amount of fat on the planet "knees" add additional length in that "leg" segment between where a human hip and knee would be. Being fatasses definitely affects them in the "leg"room department.
