How do Du feel about Michael Phelps 'retiring' && his 'last' race.?

I'm sad that this is Michael's last year, but I'm glad that he accomplished His goal this year.. To become the most decorated Olympian Ever!!! I think He went out on a bang! In His last race He got Gold! So proud of Him! Wish he continued to swim, but if He stops, I think I'll be okay with that too.
