      I don’t know. But I will do some estimating:

      We sleep for 8 hours in a day. So we are awake and blinking for 16 hours.
      16 hours = 16 x 60 minutes = 960 minutes.

      Now the rate we blink depends what we’re doing. Staring at a computer screen is maybe 3 blinks per minute. Walking in a windy dusty day maybe 20-30 blinks a minute. A good guess is probably 10 blinks a minute.

      So – 10 blinks per minute x 960 minutes in a day = 9600 blinks!

      Estimating is a really good way to get an approximate answer – often that will do.

      I’m not sure either but as Amar said you can have a good guess.

      A 16 hour day is a good estimate as we sleep on average 8 hours a day.
      I think we blink more than what Amar has said – I think we blink around 20 times a minute but it’s hard to estimate this part!

      S0 16 hours a day X 60 (minutes in an hour) = 960 minutes

      If we blink 20 times a minutes than:

      20 x 960 = 19,200 blinks a day

      But that is a guess as well!
