Your home appliance can tell your blood pressure by 2020

By 2020 there will be a billion objects connected to the internet. The new rule for the future is going to be, “anything that can be connected, will be connected.”
There are many examples for what this might look like or what the potential value might be.  Say for example you are on your way to a meeting, your car could have access to your calendar and already know the best route to take, if the traffic is heavy your car might send a text to the other party notifying them that you will be late. 

Your home can identify you and know your heart rate and blood pressure, your appliances can tell your mood through your blood pressure and play an appropriate music for you. Hmmm.....
