One of my husband's ex-girlfriends would lift weights and run every day, have 2 pots of coffee, one bagel, one can of tuna, and cigarettes. She looks great, but she's very unhealthy. She's malnourished, has fertility problems and heart problems.
So, a fit-looking body doesn't a healthy-person make.
But, her health problems and how she treats her body and all that stuff -- it's none of my business, really. She's a cool person. I accept her -- weird eating disorder and all -- and because of that, I have the opportunity to relate to a cool person.
