yawn
3-4 times on average!
1,825 times a year.
Well, a healthy person usually yawns about 4-6 times a day on average. So 5*365=1,825 times a year. Average person lives about 80 years so, I would estimate the average person yawns 146,000 times in a lifetime.
Most people yawn about average of 3-5yawns per day... Still Not Confirmed ...

you can never tell how many times you yawn because we all yawn at different rates
They yawn a whole life time

Yes, you can yawn while sleeping, I've seen it done many times.
On average the normal yawn lasts six seconds.
yawns are contagious becuase when we see another person yawn our brain sees it as that person is gasping for air and they dont have enough oxygen so as a defense mechenisme we will yawn also.
