The Olympics is defined as the modern revival of the ancient games held once every four years in a selected country (freedictionary.com)

There are the winter and summer Olympics that alternate every two years, this year it is time for the winter Olympics.

Some of the winter games range from: speed skiing, snowboarding, ice hockey, luge, figure skating, curling, bobsled, skeleton, and ski jumping to name a few. 

Some of the summer games range from: volleyball, soccer, rowing, swimming, water polo, archery, cycling, kayaking, taekwondo, judo, lacrosse, and trampoline to name a few. 

"The most important thing in the Olympic Games is not to win but to take part, just as the most important thing in life is not the triumph, but the struggle. The essential thing is not to have conquered, but to have fought well."
Olympic Creed
