"I just know within myself I wouldn't be able to give that effort for another four years and I don't really see the point in swimming through to (retire at) a non- Olympic event, because the Olympics is the pinnacle.
"I've got back down to my racing weight and my skinfolds in Beijing which I'm happy about because I haven't been there for four years.
"I'm just making sure I dot all the I's and cross all the T's now so I don't have regrets later on.
"I really wouldn't want to say I've quit or will quit after this because you never know what will happen in time, but I don't see myself swimming for another four years.
"Swimming requires so much commitment and dedication and I know if I'm not giving 100 per cent to it I'm not going to get the results I want and I don't see the point in doing something half-heartedly.''
