Worms!
Meet George Hincapie, a former bicycle racer. Well, meet George’s leg, anyway. What you are feasting your eyes on are not CIA implants or alien babies just about to burst out of his leg. This photo was taken just after he completed a Tour De France Race. By the way, if you have a fear of parasites and what they can do to the human body, maybe you should just skip this one.

George cycled in five Olympic games 15 tours. What you’re seeing here is a case of varicose veins, which basically means enlarged veins. Surprisingly, the condition is usually caused by being inactive, old age, pregnancy, standing for long periods, obesity, and smoking. As far as we know, George hasn’t been pregnant or inactive, so we’ll have to go with worms. That’s definitely it.
