Personally, I like the winter games better. Don't know if there's a deep, psychological reason for that; all I can say is that watching athletes deal with ice and snow rather appeals to me. I guess all the white stuff makes for more picturesque TV viewing, too.
Of course, the summer games has its attractions, too. The main thing is track-and-field: I especially like the drama of the sprints - the 100m, 200m, 400m runs and the 4x100m relay (men's and women's). So, yeah, I'm guilty as charged of watching the "prima donnas" of the Olympics - the sprinters.
But that's okay, because rest assured that I'll have zero sympathy for any one who
knowingly takes banned substances and gets caught. It does make you wonder how many of the Chinese athletes might be doped (whether knowingly or not), because you have to consider the intense pressure they must under to produce medals for the glory of the Communist Party. (This is the cynical portion of my post.)
Diving and swimming are the other two events I most like to watch. Yeah, the Chinese have dominated diving for years, but I will be cheering on our divers from Canada, one of whom at least has a very good chance for a medal. I wish our swim team the best as well, but, like everyone else, I will be curious to see how many medals American Michael Phelps will win - and how many records he may set.
