Consider these bicycles (both mine). This one:
is the school track star. Lean, sleek, fast, not an extraneous ounce of fat. Guys want to be him, girls want to be with him.
is the kid in your math class with taped up coke bottle glasses and a pocket protector in his polyester shirt with the top button done up. Smart, practical, will probably have a well-paying job someday, but he ain't dating a cheerleader.
