W: Do you think there are any limits to the speed people can run at? I mean, will there ever come a time when athletes at Olympic events just aren’t breaking records any more?
M: Well, we’re already quite close to that stage, aren’t we? When athletes broke Olympic records in the past, some of their feats were exciting. For example, when Bob Beamon broke the long jump record in 1968, his jump was 55 centimeters longer than the previous record and it wasn’t until 1991 that someone managed to better it. I can’t imagine anyone making such a difference nowadays.
W: Although there’ll always be those exceptional individuals who grab the headlines with their exploits.
M: Though 1 suspect that they’ll be relatively few and far between. (23)Still, newspapers and TV have to live off something and they’ll exaggerate a relatively small achievement into something far bigger than it really is.
W: Small achievement! Breaking a record even by a millisecond is always going to be pretty incredible, something enormous for the individual who does it.
M: But when all is said and done, we’re pretty close to the limits of human potential now.
W: Maybe. In the past what made a difference was when sport stopped being for amateurs and people could devote themselves to it full time, not to mention new technologies which affected shoe or track design. (24)Perhaps the next big step forward will be altering genes to produce better athletes.
M: Yeah, that used to exist in science fiction only, didn’t it, but now it really is looking more and more likely. isn’t it?
W: Yes, and not just better athletes, better everyone!
