Flawed logic

"I know what you’re thinking: I’m a pushover. I’m weak and scared and would put up with anything to keep the family together. I’m probably one of those women who would endure physical abuse. But I can assure you, I’m not. I load 1,500-pound horses into trailers and gallop through the high country of Montana all summer. I went through Pitocin-induced natural childbirth. And a Caesarean section without follow-up drugs. I am handy with a chain saw."

-from a NYT article about how one woman dealt with her marriage in crisis. Random reading material.

Isn't her logic flawed though? Just because one is physically strong does not necessarily mean she is emotionally strong.
