Wearing your all-you-can-eat stretchy pants & downing one too many egg-nogs this Christmas may affect your life expectancy.
The scrooge-like scientific research published in the British Medical Journal has found that every day people indulge in a few drinks, eat too much red meat, watch TV and casually smoke can knock 30 mins off their life.
By looking at the effects of daily lifestyle habits, scientists have been able to determine how many 'microlives' (half hours of life expectancy) can be lost by naughty activities.
Professor David Spiegelhalter, a statistician at the University of Cambridge, explained that on average a 'microlife' can be lost from smoking two cigarettes, being 5 kg overweight, having a second or third alcoholic drink of the day, watching two hours of television, or eating a burger.
However in good news, 'microlives' can be topped up by sticking to just one alcoholic drink a day, eating fresh fruit and vegetables and exercising regularly.
Scientists hope that by looking at bad habits in terms of ageing faster or slower, it will help people to make healthier choices.
