Because I don't want cardiopulmonary disease.
Because I don't want to take statin drugs.
Because I don't want diabetes.
Because I want to be able to chase my children (and grandchildren) around the park.
Because I want to run up and down gorgeous mountain ranges with my sweet, cute, hot husband.
Because I love feeling the wind against my face, and in my hair, when I'm running, or on the back of the tandem.
Because I want to live, not just exist.
And if it takes funny shoes and spandex and my wiggly parts wiggling even more than usual,
I'll do it.
