If you happen to be searching for a petit, left-handed, half-Jewish, 40-year-old, divorced veterinarian with two kids, you're in luck! I bet $5 that there's someone online right now cruising profiles who fits that exact description. That's not to say you should be so picky, but here's your chance to really quantify what you want in a romantic partner. Ask yourself what if s/he smokes, has or hates pets, lives far away, is or isn't religious, does or doesn't want to have children, etc.? With, by some counts, over 90 million people online, don't settle. To bastardize the lyrics of composer Jerome Kern: "If smoke gets in your eyes, don't date a smoker."
