Follow the advice and add 13 years to your life

A large-scale American study shows that five life style factors have a major influence on how long a 50-year-old can expect to live. On average, those who follow all five pieces of advice live 13.1 years longer than the ones, who do not:

1. Do not smoke.

2. Eat a healthy diet.

3. Exercise regularly (at least 30 minutes/day).

4. Stay slim (your BMI must be 18.5-24.9).

5. Drink moderate quantities of alcohol (5-15 g/day for women, 5-30 g/day for men).
