Bicycle
The other day, I saw a bicycle that I really wanted to buy. Biking would be incredible exercise for me and something that I adore. But I haven't ridden a bike in almost 25 years and, during that time, have had surgery on both my knees. They aren't the strongest things in the world despite my efforts to build them back up after the operations. I'm afraid that, if I tried to ride a bike on any surface that had even the most remote incline, my legs would break off at the knees like two sticks only to be snatched up by wild dogs to be buried in the remote forests of Upstate South Carolina. And there I'd be lying in a ditch, whimpering and sulking at the loss of my appendages, waiting to be picked up by some benign hick with a soft spot for legless bikers.
So I didn't buy the bicycle.
