On average we live for 78.3 years. Most of us remember people we meet after age 5. Assume we interact with 3 new people daily in cities, 365 days in a year plus leap-year days is 365.24. In total it will be (78.3 – 5) x 3 x 365.24 = 80,000 people. Is it a lot? How many people will you impact this life time?
