This is not a joke but a real British research conducted among 20 000 healthy British men and women from 1993 to 1997.

Participants were asked about their lifestyles and also have their blood tested, as well as their Vitamin C intake measured (Vitamin C is an indicator of how much fruit and vegetables people ate). All participants were middle-aged and older (45-79).

Here are the four small changes you need to do in order to improve your health and add 14 more years to your life:

1. Quit smoking
2. Eat fruits and vegetables – 5 servings every day
3. Exercise regularly
4. Moderate drinking

Quit smoking comes first as it has the greatest benefit – it gives up to 80 percent improvement in your overall health condition. Second is the fruits and vegetables consumption as it has the second great benefit to prolong your life.

Moderate drinking and exercising regularly have equal benefits and both share the third position. However, they are listed that way to keep the list simpler and clearer. This way you’d remember you have four things to pay attention to in order to change your lifestyle, not just three and to skip number 4 because it’s equal to number 3.
