Steven Green is noting on Insty that your smart watch can know you're sick sooner than you will.
I expect that one of these days I'll be out walking the dog when I round
a corner and see an ambulance parked along side the road with 2 EMT's
with the paddles ready, a gurney, with a sign of the sort one sees at
the airport with my name on it.
If I didn't need them before, I probably would after seeing this.
Smart watches will be issued to everyone by the government so at the first sign of your impending demise it can summon an ambulance, notify your insurance company, and should your pulse rate fall to zero, notify your widow and change your voter registration to Democrat.
