On March 30, Bruce Willis' wife, Emma Heming Willis, took to Instagram to announce her husband's retirement from acting. The statement explained the reason behind his early retirement was a recent diagnosis of “aphasia, which is impacting his cognitive abilities.”
Aphasia is defined by the Mayo Clinic as "a condition that affects your ability to communicate," whether it be verbal or written. As one can imagine, this diagnosis might have an impact on an actor regarding memorization and delivery of lines.
Heming Willis' post didn’t go into any additional details about his health status. Instead, the Willis family's letter to the actor's fans asks for their continued support and pledges to "live it up" as a family during the actor's retirement.
