With its beautiful parks, walking trails, and inviting climate, residents are encouraged to build low-intensity physical activity into their daily routines, fostering both physical health and community connection.

Residents could benefit by actively seeking opportunities to “down shift” and prioritize walking or cycling for local errands, further enhancing their well-being and mimicking the integrated movement seen in Blue Zones.
