Is it me or is it safe to assume that all obese women first letter begins with M and end with A?

I was watching women 58 through 70 who have had babies late in life for some it was the first child...Why? The sad part about it was these women looked absolutely stunning for their age and made caring for a baby look so easy. These women planned the birth of their babies and were doing all things possible to maintain a healthy life.

Speaking of healthy I then watched a segment of Clinically Obese women having babies. My questions is why do all of the obese women's first letter in their name start with the letter M and end with the letter A? For Example Melva, she is obese....
