How long will you live?
Everyone wants to live a long and healthy life. Today, many
scientists are trying to find the habits that help people live
longer. In 1970, some scientists talked to 7,000 people in the
United States and got information about ___________ habits.
Then they checked to see how long the people lived.
The scientists learned that the people with the longest
lives did seven things. (1) They ate breakfast every day. (2) They
didn’t eat snacks between meals. (3) They weren’t too heavy or
too thin. (4) They exercised regularly. (5) They slept seven to
eight hours every night not more, and not less. (6) They didn’t
smoke. (7) They didn’t drink more than two alcoholic drinks per
day.
These were the habits that made a big difference. People
who did all of these things lived 12 years longer than people
who did only one to three of the things.
Scientists say that you should change your habits slowly.
Make one small change every week. You need about 21 days to
make a new habit.
