And SHE KNOWS BETTER.
Sure, all the candidates know better -- but many voters don't. They believe what they want to believe. For example when gas prices go up under a democrat president you'll hear right-wingers crying about how the president causes it and left-wingers claiming he doesn't have control. When the prices go down you'll hear right-wingers claiming he had nothing to do with it and left-wingers claiming he made it all better. Vice versa for a republican president. Nobody cares what the president can actually do when they are at the polls, they only care that what the candidate said resonates with their world view, however rational or bat-shit crazy it may be.
You and I can tell the difference between a blind campaign promise and a plan for something that's actually achievable, but many people either can't or won't make the effort to do that. That's what drags our political discourse down a series of tubes. We, collectively, get the candidates we deserve. The fact that the best candidates available right now are people like Donald Trump is a reflection of our own society, sadly.
Wait! Your shirt has a back pocket? Tell me more about this marvel of modern fashion.
I can't tell if you're serious, but in any case cyclist's shirts have pockets along the lower hem on the back because they are out of the way when you lean forward and because pockets on your legs would be difficult to used due to leg movement. It has nothing to do with fashion and everything to do with function.
Agree with the rest of your comment though -- bike computers that do everything have been on the market for decades. Not to mention existing fitness watches that also fill the same market.
