Hmm - I got to agree - the open work-out seemed a bit off. And yeah - during the follow-up interview, he did mention injuries and age and him thinking more and more about retiring. Though, this is in part because of the persistent questions regarding his age from the journalists, who probably also felt something was off during the open work-out, hence their question about his current energy levels as opposed to how much energy he had in the moments up to his previous fights.
