Michael Phelps, the most successful Olympian ever, came under controversy during London 2012 when he admitted that many swimmers "pee in the pool" especially during long training sessions.
He also said it was OK to relieve yourself in the pool as the chlorine killed any germs.
Now, scientists have confirmed that at least his facts are right, the Telegraph reported.
Sense About Science (SAS), a charity which aims to dispel commonly held myths, especially those promulgated by celebrities, congratulated him on being scientifically correct.
In fact, biochemist Stuart Jones, said that urine is essentially sterile so there isn't actually anything to kill in the first place. (ANI)
