The average person is awake for about 14 to 16 hours per day. Most could extend that to about 20 hours if they were to stay up later; up to 40 hours is easy once a person gets beyond the 24 hour mark; longer than 60 hours (staying awake straight through two nights and three days) is rare, but doable; the record is 264 hours or 11 days straight. Hannah Griffiths.
The average person tends to blink between 10 and 30 times per minute. Therefore, taking an average of 20 blinks per minute, this would mean 1200 blinks per hour (20 x 60) anâ¦d lets say the average person is awake for 14 hours a day (we don't blink in our sleep) then on average we blink 16,800 (1200 x14) times a day!
