While at the Tiger Hill garden we learned from Joe that when a child is first born they are considered one year old. Also if the child is born after the Chinese New Year they are considered two years old. I was really confused by this until he said that he was born in 1983 and called himself twenty seven years old. Katie was also born in 1983 and she is called 25 years old in the United States. This way of age really surprised me. How does this affect the expected lifetime of a person when dealing with insurance of statistical data. Does this apply when they are traveling internationally? I also want to know how this custom began, because when a person is born how are they even seen as having completed a year. How does having a Chinese New Year occurring after you are born seen as another year. I just want to know why this is considered a completion of a year of life.
