Whether or not you smoke might be something to consider when looking into your global medical insurance needs.
According to recent comments from Alison Walsh, youth advisor at independent charity QUIT, the physical addiction to nicotine is only one half of a smoker's problems.
If you are trying to quit then you also have to deal with the emotional or psychological addiction as well, she explained.
"The cravings can be very much habitual – say, if you have a cup of tea you'll have a cigarette to go with it; it's a way of killing time, a way of taking a break," Ms Walsh remarked.
"Our message is really that you can still have that, but leave the cigarette out when you do."
According to the World Health Organisation, Guinea has the highest percentage population of smokers at 51 per cent.
Meanwhile, Senegal has one of the lowest rates at just four per cent, closely followed by the United Arab Emirates at nine per cent.
