People don't blink when they're asleep. In a 24 hour day, most(?) people sleep for eight hours, so 15,360 would be a lot closer for an entire day. Also, anyone who uses a computer blinks a lot less than normal.
These are replaced at a rate of about 2 million per second (again, from wikipedia). There are 86,400 seconds in a day and so: (2 million x 86,400) + 50 to 70 billion = 222 billion to 242 billion cells produced every day by the average human body. Note, this is for the average adult. The rate of red blood cell production slows as you grow older. In order to understand this, we need to understand cell division.
