     "Christmas comes but once a year" is a familiar phrase, and indeed for many people the 25th of December

is the highlight of the calendar (日历).

     But for one British man once a year is not enough. Andy Park, who is better known by his nickname

Mr. Christmas, has celebrated Christmas every single day for the last 14 years.

     The 44-year-old electrician claims to have eaten a full roast dinner every day for the last decade and a half,

munching over 5 000 turkeys, 117 000 Brussels sprouts, and around 30 000 roast potatoes in the process.

     He also sends himself a Christmas card every day and looks forward to unwrapping a present he has

bought himself each evening, while watching the Queen's Speech.

     Mr. Park estimates his festive love costs him £150 (1570 yuan) a week. This year, however, he says he

is short of money for his celebrations due to the global financial crisis.

     His Christmas habit is affecting more than just his wallet. Mr. Park was previously warned by his doctor

that his Christmas addiction could kill him. His habit has caused his weight to 121kg.

     So how did Andy Park's strong desire for Christmas begin?

     "I'll never forget the day it started," said Mr. Park. "The sun was shining, but I was just feeling fed up and

bored, so I went home and put the decorations up. Suddenly I was happy. I thought, this is fun. So I did it

again the next day, and the day after that."
