This article indicates that a shark attacked and killed a triathlete swimming in the ocean near San Diego.
You'll note that it says "killed," not "ate." That's because the shark figured that men who wear sleeveless jerseys, stick food to their bicycle frame, pee on it, and never stop to have an espresso and a biscotti and to generally appreciate la buona vita, are basically tasteless.
Ps. To my triathlete readers: No offense. I'm just busting your chops. I'm sure you all taste great, especially if you've just used bacon-flavored Pam to lube up and squeeze into your wetsuit.
