For many people.leisure time is an opportunity to get outdoors,have some fun and meet interesting people.Add two pieces of advanced 21st century technology—global positioning system (GPS) devices and the Internet—to get "geocaching".

The word geocaching comes from “geo” (earth) and “cache” (hidden storage).Geocachers log onto a website to find information about the location of a cache—usually a waterproof plastic box containing small items such as toys and CDs—along with a notebook where “finders” can enter comments and learn about the cache “owner”,the person who created and hid the cache.Finders may take any of the items in the cache but are expected to replace them with something of similar value.They then visit the website again and write a message to the owner.

Geocaching became possible on May 1,2000,when a satellite system developed by the U.S.Department of Defense was made public.Using an inexpensive GPS device,anyone on earth can send a signal to the satellites and receive information about their position.This is basically a high-tech version of orienteering,the traditional pastime which uses maps and compasses instead of GPS to determine one’s location.

Geocachers are a very considerate group.Owners carefully choose a cache’s location to give finders an enjoyable experience,such as a beautiful view or a good campsite.They also consider the environmental impact of their cache since it could result in an increased number of visitors to an area.As for the content of the caches,owners and finders must only use items that are suitable for the whole family,as caches are found by geocachers of all ages.

Higher income has already been linked to greater longevity and better health.A new study by a famous researcher suggests geographic location plays an key role in life expectancy(预期)for lower earners.That means if you're poor,you're likely to live for longer in a city like San Francisco or New York than in a city like Detroit or Cincinnati.

Being rich anywhere broadly means enjoying good health anywhere,but location is a key factor in health for people in lower income groups.Michael Stepner,one of the study's co-authors,said economic decline and decreasing populations in the Rust Belt aren't necessarily to blame.

The study found that location matters for low earners.Low-income individuals tend to live more healthily and for longer in cities with college-educated populations,high incomes,more immigrants,and high levels of government expenses,such as New York and San Francisco.The study also found measures of health—insurance coverage and health spending were of lesser importance than social and economic factors in determining health for low-income individuals.Nor did having health insurance seem to be a factor in increasing life expectancy for poorer groups."The key driver of differences in inequality across areas of life expectancy is probably not access to health care,"Mr Stepner said.
