Brookline’s Turkeys: Friends or foes? Jackson Machesky / [email protected] When Brookline resident Irena Tsvetkova left her home on an early-morning walk April 11, she was expecting a couple of hours of meditation and relaxation. Instead, she found herself screaming for help, a pursuer hot on her trail. “In the morning, when you meditate, you’re in an alpha state, and when you’re stressed, you’re in a beta state,” explained Tsvetkova, who works as an associate for international economics consultant firm Analysis Group. “I was certainly in a beta state. This was not the relaxing morning I was going for.”
