I can't believe sometimes how successful a swimmer Michael Phelps is!
It is quite impressive. I dont even know how to swim. Do you?
Well I can swim but not that well.  He is the most decorated olympian of all time...with a total of 28 medals
Has he retired?
Yes after the last olympics he retired actually.  
I have never watched the olympics, I am watching the world cup though
wow that is so interesting that you have never watched the olympics!  He actually hold the record for the most gold medals as well at 23 gold medals
Oh that is fantastic. I can tell you are a really big fan.
ha ha yeah I enjoy swimming at the olympics.
