That depends on what age his heart stops beating.
During an average lifetime: over 2.5 billion times.
The Sun has been alive for 4.6 billion years and is estimated to continue for another 5 billion years. See related link for a pictorial of our Suns estimated life cycle.
It is estimated that during one's lifetime they will be admitted to a hospital every 17 years and be seen in an emergency room every 3 years
The average heartbeat in an lifetimes is 2 and a half billion times
Elvis Presley sold One billion in his life time!

Everyone is different, but the average is estimated at 3.04 billion.
6,967,400,000(October 10, 2011) -------- As of 2017 it is estimated to be about 7.5 billion
The estimated number of galaxy mergers, given that there are 100 billion galaxies in the universe, is 100 billion.
The estimated number of satellite galaxies, given that there are 100 billion galaxies in the universe, is 170 billion.
There are an estimated 100 to 200 billion galaxies.Scientists estimate that our Galaxy (The Milky Way) contains 200 to 400 billion stars.So taking a conservative number of 100 billion stars per galaxy, gives an approximate total of 10,000,000,000,000,000,000,000 stars. (which is 10 sextillion)It is unknown. The Milky Way galaxy contains an estimated 200 billion stars and there are an estimated 100 billion galaxies in the observable universe. However, our galaxy is significantly larger than most. That said, if we assume the average galaxy has 10 billion stars then we arrive at an estimate of 1,000 billion billion stars, or about 1 sextillion stars.
The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.
