Every athlete grows up looking to take part in the Olympic Games which is the world's foremost sports competition.
We take a look at the five Olympic records that will never be broken.
Jong & Cerdena gold-medal exhibition displays
South Korean star Kwon Jong Yul and Filipino legend Arianne Cerdena won gold medals in bowling at the 1988 competition.
However, bowling was only a demonstration sport at the Olympic Games which were hosted by Seoul, South Korea.
Nevertheless, Jong and Cerdena etched their names in the record books and their record will never be broken.
This is because the sport has not played in the Olympics since.
Comaneci's perfect 10
Retired Romanian gymnast Nadia Comaneci, who is a five-time Olympic gold medalist, all in individual events, stunned the whole world at the 1976 competition.
Comaneci became the first gymnast to be awarded a perfect score of 10.0 at the Olympic Games at the age of 14 in Montreal, Canada.
The gymnast icon did it a total of six times and it earned her three gold medals making it impossible for anyone to break her record.
The only thing possible is a tie with it which means scoring 10.00 from all the judges three times.
"I don't think there is pressure in the competition. I think it's the other way around. You don't have pressure when you are a child," Comaneci said on CBC.
"You become to [feel] pressure when you are an adult. From my experience, I was 14. I competed, I had no pressure. What kind of pressure can I have? I mean, I just go up and do a routine. I've done thousands of them back home."
13-year-old sensation Gestring wins gold
American legend Marjorie Gestring won the gold medal in the 3-meter springboard diving event at the 1936 Olympic Games in Berlin, Germany.
As a result, Gestring became the youngest person ever to win an Olympic gold medal at the age of 13 years and 268 days.
Her record has stood the test of time and it is almost impossible to break the record which was set 84 years ago.
Just imagine a 13-year-old winning an Olympic gold medal?

Millar’s astonishing consecutive Olympic appearances
Ian Millar has been a regular in the last 10 competitions while some athletes can only dream of participating in the Olympic Games at least once.
The retired Canadian equestrian team athlete for showjumping holds the record for most Olympic appearances by any athlete in any sport (10).
Often nicknamed "Captain Canada" due to his longevity and accomplishments in the sport, Millar appeared in 10 Olympics, since 1972.
It will be almost impossible for anyone to break Millar's record as he or she will have to take part in five successive competitions (40 years) which is unthinkable.
Phelps’ extraordinary 23 gold medals
Michael Phelps is the most successful and most decorated Olympian of all time, with a total of 28 medals.
Nicknamed the Flying Fish, Phelps also holds the all-time record for Olympic gold medals (23) having dominated the swimming world between 2004 and 2016.
Well, that is quite impossible to break because the next closest to Phelps' mark is retired Soviet gymnast Larisa Latynina, who won nine gold medals.
For someone to break the Phelps' record, he or she will have to accumulate at least six gold medals per cycle which is impossible.
"Swimming is a drug and he's addicted. London made him mortal but the immortality is back," five-time Olympian Mark Foster told CNN about Phelps.
"But I've never seen a crowd more in love with him than in Brazil. They're just so into Michael Phelps, he has that effect on people. It's like watching Usain Bolt, everyone goes bang and realizes its something special. But here they realize it's finally the end of something special."
