If you thought blowing out this year's birthday candles was tough then think about this...
A third of babies born in 2012 in the UK are expected to live to 100.
Experts at the Office of National Statistics looked at how long people are living at the moment to figure out the new number.
The number of centenarians has been going up for the past 50 years with improvements in medicine and technology helping people to live longer.
Back in 1961 there were only around 600 centenarians in the UK but by 2010 there were almost 13,000.
More women than men are expected to reach 100 as traditionally women have a longer life expectancy.
