Few months back I composed mail using Gmail at midnight 11.00 PM. When I clicked Send button,
Gmail asked me few simple mathematical problems. I am more interested to solve mathematical problems.I had just answered correctly. My mail had been sent.
I tried second time with wrong answers, but Gmail asked me few other similar problems. Gmail allows the composed mail to be sent after giving correct answers.
When I send mail to the same friend next day morning, Gmail didn’t ask me the same questions. I had a
question in my mind “Why Gmail is asking me mathematical problems only at night time?”
I never made effort to know answer for this question rather I assumed it’s for security reason.
Again Last week I used Gmail at late night. Gmail prompted the same kind of mathematical problems when I clicked send button. This time I want to go beyond my thinking and eager to know the answer for my long-lasting question. I got to know this is a Gmail Lab feature. This feature name is,
