I was told that it would never end at the rate of the population
growth, and with the number of people there. Well, one person will
pass you every 1.5 seconds. There are 1.3 billion people on china.
1.3 billion times 1.5= 1,950,000,000 seconds divided by 60= 32.5
million minutes divided by 60= 540,000 hours which is about 61
years! It will take the entire population of China about 61 years
to pass you!!!

## But,

Then all the people who were born during that 61 years have to
pass.

## So,

Given：

China's Total Population (2007) ＝1.32129 billion (official
number),

China's Population Growth (2007) ＝6.81 million (to make it
simple, we suppose this number doesn't change over years), and

Time Needed by Each Person to Pass You ＝1.5 seconds (taken from
the text above).

Now we can calculate as follows:

People Past You Each Year ＝365×24×60×60÷1.5 ＝21024000

"Net" People Past You Each Year (deduct the annual growth)
＝21024000－6810000 ＝14214000

**Total Years Needed** ＝1321290000÷14214000 ≈ **93
Years**

## Hence,

I wish you a long life! :-)

## Note:

The math used above is a simple linear equation, whereas population
expansion more closely resembles an exponential model (in essence,
as there are more people there are more children, who then have
even more children, so each generation is more populous). The
reason you heard that it would never end due to reproduction is
that the exponential model grows very big, very fast. That model is
also flawed, however, and the truth lies somewhere between the two
values.

## Humorous Note:

It would be tough for them to reproduce if they were constantly
walking toward you. And really, how mean would it be to send their
newborn children to the back of the line?
