For Men, Having a Twin Sister Increases Anorexia Risk

I Lost a Bet

If you are a guy with a twin sister, it looks like your chances for anorexia are higher than the normal individual. Why? Because you might have more ESTROGEN in you!!!

Researchers Dr. Marco Procopio and Paul Marriott analyzed more than 4,000 Swedish twins born between 1935 and 1958. In their research, they found that overall, women are still more likely than men to develop anorexia, an eating disorder in which people literally starve themselves due to a fear of gaining weight.

Why might these men be at greater risk? Procopio and Marriott suggested that hormones could be a major factor.

Specifically, they wrote in the study, the male of the opposite-sex twin pair may be exposed to more estrogen in the uterus from the development of their female twin.

Wow, what a discovery. Traits also found in male twins not mentioned, include increased fashion sense and a tendency to nag. I guess there’s a silver lining to all this.

If this theory holds true, does that mean that Simon cowell has a twin sister somewhere out there?
