Case in point : Naman Keita.

One of the few well known french athletes.
Won bronze medal in the last olympics individually and a few medals with the french 4 x 400 meters.
Just tested positive at testosterone a few days before the world championship ( where is was quite bad ).

This is an athlete, partly paid by the french federation, with a coach of good reputation, who wasn't very good this year and apparently hurt his stomach muscles during the french championship.

So what does he do ?
He ask all the people at the federation ?
He talked about it with his coach ?
He tried to see big names doctor ?

No, some "friend" recommend him some "good but inoffensive products" that he ordered on the internet and took without asking anyone...

So :

1. he really is stupid !
2. he really think we're stupid !
