Olympians.

Overall, I can't stand athletes.  They tend to be very limited, group-think, closed-off people; I've never met athletes who've been judgmental of me or anything, so that's not it, I just don't get the sense that they're engaged by too much and in love with the world.

They also tend to not develop themselves in other ways, so as they age, they become has-beens...  So many of them slide into coaching later on, and just enter like decades of stasis, it seems.
 
I've met some interesting people who were athletes, but they all tended to be uncomfortable with the culture and separate themselves or drift away from it.

For example, one undergrad I met at school used to be a gymnast, but that got old, and now does a lot of drugs and makes psychedelic (sp.?) music.

Another used to be on the swimteam, but it wasn't for him, and still keeps in touch with those people, but began doing investigative journalism and other things and developing other parts of himself.

We had like a 40min. conversation, too, about bestiality and guys who like to get f*cked by horses but say they aren't gay, and he told me that the swimteam watches a lot of sicko porn together like that.

In any case, all the shiny 19 year-olds on the Olympics just gets me, the whole "moment of glory" thing is so weird.  All the attention the athletes get makes me think of what kind of people they are, and what their later lives will be like.
