I'm not.

At my last physical (January), my blood work came back perfect. By all rights I should be a diabetic, and a poster child for potential heart attacks. That's one big reason I started bicycle commuting in the first place. But, according to my doctor, "there is absolutely no reason on Earth your numbers should be this good". I fall right into the normal category - on the good side of the normal category - on all my blood numbers.

My wife is thoroughly disgusted by it.
