It's not like a paper map you fool. And yeah it's not hard to come up with a drug. Testing it is the problem. Stick to what you know - might not be very much I realize.
Oh wow, "coming up" with a drug is easy! Maybe you should go to Pfizer or BMS and give them some ideas since their pipeline is so shallow. You can say "He blokes, here's a bloody molecule that cures 'diabeetus' and it don't get metabolized by any CYP450 enzymes and it's elimination is not affected by renal function. Go test it mateys!"
You would be rich mate! And by the time you retire, the geniuses at Apple might have caught up to Microsoft, Google, Mapquest, Tomtom, Garmin, and the many other companies who already managed to do maps as a side project.
gday matey!
