According to Bolt, Mills once said to him : "I don't worry about you when you're unfit. It's when you're strong that I stress because your testosterone goes high - through the roof. You have the potential to get yourself into trouble." "Going out occasionally, dancing and chilling with friends was a release valve from the pressures of living in the spotlight," [Bolt] added. "It helped me to work properly on the track and nobody, nobody was going to tell me otherwise."
