How many people on average does a person meet in their lifetime?

For an average person (not working in hospital, she/he is not a sales personnel, etc..):
Average meeting # in a day - for every day: 3*
Average lifetime - world statistic- : 67 (exclude the childhood period till 5 years)= 62

62years X 365days X 3 people= 67.890 people on average

*this is my estimation for an average person
