Google Now tells you on the first of the month how many hours you walked
Been getting it for over past 3 months.
Try to speak 'ok, Google'
'who is Barack Obama?'
After you get the answer say again 'ok, Google'
'and how old is he?'
Interesting to see how it connects the two searches.
But that doesn't work in regular google search. it would be just like doing an initial search of 'and how old is he'.
