Wearable gadgets - Are we heading towards a gadget driven environment?

I happened to see a BBC link, that shows the potential of an upcoming wearable gadget, that can detect possibly Cancer and heart-attack detector. By this, we have advanced one step close to being a slave to machines.

Google is developing cancer and heart attack detector

Gone are the days, when medical practitioners hold the pulse for a minute or two, do the most possible closest diagnosis, provide a simple herbal based medicine and charge a nominal amount. Life with simple health issues like common cold and fever were never given respect and we were told not to glorify simple diseases.

Now, with these kind of gadgets, we are heading towards a World where even common cold and fever would be detected by a wearable gadget. And there can be a situation where a gadget can alert you on an upcoming sneeze, so that you can say 'Excuse me' even before you sneeze.

In the days to come, the human body may be fitted with all types of Gadgets and who knows, we may even be asked to touch a "live" electric wire to charge the gadgets via our body. That will be awesome.

I can only be at awe on Sujatha Rangarajan ability to foresee this kind of things in his "Jeeno" and "Meendum Jeeno" novels.
