He's been to Grenoble, France in 1968, Montreal in 1976, Atlanta in 1996 and Beijing 2008.
"I'm very interested in international relations. I'm very interested in sports and of course, the media. So, of course, you combine all those and throw in a little politics and that's what the Olympics are," said Purvis.
Purvis said these winter games are different for a few reasons.
"Really, the big concern here is security more than anything else. That's a real legitimate concern, I'm afraid. Another concern is the relative remoteness of the location," said Purvis. "It's not the easiest place to get to. The accommodations are somewhat limited and in some cases, somewhat primitive."
Even if fewer fans show up, Purvis thinks you might not be able to tell, that is, if Russia's President Putin has control.
"In terms of attendance, it may be relatively low. Although, I think Mr. Putin and his associates would do everything they can to make it appear very well attended," said Purvis.
No matter where the events take place, the games remain an international spectacle.
