Idea: "An apple a day keeps the doctor away", however all of us eat apples, and all us go to doctors. Some of us go to doctors only when absolutely necessary, while the others are more disciplined and believe in regular checkup/feedback. Most of the time during these regular checkups, the doctors consult your report and give you a prescription, a suggestion (e.g. eat more fruits, drink less coke), a tip (e.g. walk 20 minutes after lunch), or a combination of these, mostly in order to take some preventive measures. What if we could have all our medical reports (in a standardized format) online, and run an analysis tool which can email us (or send us an SMS or place an automated call) and gives us very similar feedback? No more making appointments for routine checkups, no more waiting in lines, no more taking time off during a working day, and no more doctor's consultation fees. If the analysis tool finds something alarming, it can ask you to consult a doctor (or send an ambulance for you right away).
Reward: "Health is Wealth!", you happy soul is the biggest reward you could get.
Bonus: A click a day could keep the doctor away!
