Marcus is talking to his therapist about his phobia of birds.
"I am absolutely terrified of birds, especially pigeons. When I see one, my heart races and I freeze on the spot. I cannot walk through the town square anymore because there are always flocks of them, and I've stopped eating lunch outside in the park. If I hear wings flapping, I panic and run away."
Explain how the therapist could use systematic desensitisation to treat Marcus's phobia of birds.
