Some people are blessed with great genes and seem to be able to eat whatever they want and not work for their beautiful bodies. I am not one of them. Most of my relatives on both sides are somewhat overweight. I have to watch what I eat and exercise just to avoid becoming a large mass of soft flesh. It has not helped that my career position has changed from frequent travel to a sedentary desk job due to the pandemic.
I am a nude model for artists. For those who aren't familiar with life modeling they assume it requires a great body. Although some models do have beautiful bodies, many do not. Artists and art students seem to enjoy the variety that comes with all body types. There are different challenges depicting a muscular body versus one that's obese. With my body, I feel like I have to work harder to hold poses where I am adding as much definition as I can and also simply finding interesting poses so the lines of my body look their best from all angles.
Lastly, if you have not heard the term "artistic license" it is something that enables the artist to alter what they see to create what they believe to be a better piece of art. As I get older I think there will be a whole lot more of it!
