On January 19, 2013, a few days before my 75th birthday, I plan to bicycle for 75 miles to encourage people to make donations to the Prostate Cancer Foundation. No, I don’t have the disease. I don’t even have a prostate, though I’m often prostrate at the end of a long, hard workout. As a woman, maybe I should devote my energies to curing breast cancer by focusing on the Mamma Jamma Ride, the Race for the Cure, and so on. In a small way, I have supported (and will continue to support) these and other nonprofit athletic events for as long as I’m financially able.
