OK. Wow! Are you even serious?
Do you measure the inside curve or outside curve of the banana and decide what is the best measurement for your needs?
Do you think the distance between 2 cities changes with adding roads?
And back to the NBA stars. How do you think they measure their height? Starting before the toes, following the curve to the leg, then up (maybe even measuring also the erect penis, why not?), follow the curves of the six pack etc? Or do you think they measure straight from the floor to the head, flattening the possible hairs on said head?
