When Segway met Lunar Rover.

Cool idea. Hope it doesn't need to get refueled every 15 minutes.

Don't touch that, you don't know where it's been.

You know the routine. You come to the clinic, you say you've got a sore throat and some fever. The doctor checks you up, says "open your mouth and say aaaaa". He says you've got an inflammation. He takes a test sample from your throat and sends it to the lab. He says the results will be in in a few days. In the meantime, start taking antibiotics, just in case. You reluctantly agree, start taking the stuff, and in 3 days discover it was just a virus. There was no need in antibiotics in the first place, and you've just pumped yourself full of some questionable drugs.

Well, it has all changed. In my recent visit to the doctor, the whole lab test took place right there, in front of my eyes. A quick swipe of your throat, the cotton tip applicator goes into a small test tube, and in five minutes (I kid you not) the color shows - germs, or no germs. We live in a wonderful age indeed.
