A few things in life are certain: death, taxes, cardio (I suppose diets fit here also, but we're not talking nutrition for another few weeks) and Uber. Eventually, you and I will die. Every year around this time, we also have to pay our taxes (or hopefully get a refund!). If you ever visit or live in an urban or metro area (even suburban areas now!), you will almost certainly ride in an Uber, even if like me, you have never personally downloaded the app and called for a ride.
