Thank you for asking ! I ' m happy to help you with your question . \n To determine the average number of bl inks a human makes in a lifetime , we need to consider several factors , including the average person ' s age , bl ink rate , and lif es pan . \n First ly , let ' s establish the average bl ink rate for a health y adult . According to various studies , the average bl ink rate for an adult is around 6 - 1 0 bl inks per minute . This means that a person bl inks approximately 1 2 , 0 0 0 - 1 8 , 0 0 0 times in an hour , and around 2 5 2 , 0 0 0 - 3 6 0 , 0 0 0 times in a day . \n Now , let ' s move on to the lif es pan of a human . The average lif es pan of a person is around 7 0 - 8 0 years , depending on various factors such as l ifest yle , gen et ics , and health conditions . \n Using these numbers , we can estimate the total number of bl inks a person makes in their lifetime . Let ' s assume that a person bl inks at an average rate of 8 bl inks per minute , which is a reasonable estimate . \n If a person lives to be 7 5 years old , they will have bl ink ed approximately 2 5 2 , 0 0 0 times per day x 7 5 years = 1 8 , 3 0 0 , 0 0 0 times in their lifetime . \n However , it ' s important to note that this is just an estimate , and the actual number of bl inks a person makes in their lifetime can vary significantly depending on various factors such as eye health , l ifest yle , and gen et ics . \n In conclusion , while there is no definit ive answer to the question of how many times the average human bl inks in a lifetime , we can estimate it to be around 1 8 - 2 0 million times based on the average bl ink rate and lif es pan of a person . However , it ' s important to remember that this is just an estimate , and the actual number can vary significantly . </s>
