To no-quiero,

your judgement is biased. If not michael, who do you think is the greatest olympion? It's been 36 years that Phelps broke the record of Spitz. In every olympic, there is someone different who sets world record in 100 m race. you think this person should be called the greast olympion. If you do it, then you misuse the word "the gretest olympion". Whats wrong if Michael is called the greatest olympion. you have egomania, may be you never accepts the . I respect Mr. Bolt who has become the fastest man in the world. There are more than dozens of events in track. you could compare usain with michael only after  he wins couple of races.

Be positive and appreciate others success.
