Bad habits reduce life expectancy

Who would think that an extra glass of wine at night or spending a couple of hours in front of the television could reduce your life expectancy? Well, according to a University of Cambridge statistician, this is exactly what happens.

David Spiegelhalter, whose article was recently published in the British Medical Journal (BMJ), has used microlives, a period of 30 minutes, to explain by how long a bad habit can reduce your life. For example, smoking two cigarettes will cost you one microlife, as well having a second alcoholic drink, watching two hours of television and being five kilos overweight. And having an extra portion of red meat every day during a lifetime will reduce a man’s life expectancy by about one year.

There is good news however, with women having four more microlives than men and you can gain microlives if you change your habits. Stick to just one glass of alcohol per day and you gain an extra 30 microlives in a lifetime and five servings of fruit and vegetables per day will gain you an extra two hours.

The statistics were compiled to help people breakdown the effect bad habits have on their life expectancy.
