Question : Why Are Fat People Good at Singing?

Why are fat people so good at singing?
Is it because they have super natural stomach power that regular people don’t possess?
I would think that fat people have a harder time singing because of breath control..
But it seems as if their voice is a lot more powerful and stronger than the regular folks.

Anyone care to share some insight on this matter?

And…since J-Hud and Adele are now thin, how come they still get to keep their voice?
